I would like to know if iOS distribution I can use for various applications, for example I used my iOS distribution in the application to it is already in production now I want to use this same iOS distribution in application b to also put into production is this possible?
Certificates are just a private and public key pair. You can use single certificate for signing multiple apps. But you need a separate provisioning profile for every app. Every app must have a unique bundle identifier. If you explore developer account and create a new provisioning file you will be able to select your old certificate in it.
you can use one certificate for multiple app but you bundle identifier (i.e com.yourappname.complanyname) should be different for each app
A certificate/driver license/ID card is attached to an author/app publisher†
A single author can have thousands of books/apps.
For each book they will dictate who can download it. e.g. only people with these email address can download this books.
Hence every book needs an email list/ provisioning profile.
†: Each certificate is created by the developer's Macbook. A user doesn't need multiple driver licenses to identify himself, yet he can create multiple ID cards for himself. In the real world a user can't have multiple driver licenses of a given state. But in the world of computers, I could create 100s of certificates for myself. Each certificate would have its own expiry date. The certificate will become invalid either by reaching its expiry date or by manual revocation through apple developer portal.
In the image below you can see that the certificate has an expiry date and that I can also revoke the certificate at any time:
To learn more about revocation and its effect, I highly recommend you to see If I revoke an existing distribution certificate, will it mess up anything with existing apps?
No you can not do this. One certificate corresponds to one app. You have to create another certificate for other app

We are struggling with the Distribution Certificate handling from Apple.
We have several developers setup in the Apple Developer Portal, for the sake of the example:
Alice: Team Admin
Bob: Admin
Charles: Admin
Dan: Developer
Alice, Bob, and Charles should be able to build Apps for Distribution (Adhoc for internal testing, Testflight for external testing, and Appstore for distribution). Dan is only producing code and debugging on his local machine.
All users use individual accounts for the development.
From what we understood from the Apple documentation, Alice, Bob, Charles need a valid distribution certificate. If xCode generates it for them, they will start playing “ping pong”, and keep revoking each other’s certificate – at least this is what appears to be happening at the moment.
We are not sure why this would happen. One would think, that if you create a different new user this account can also maintain his own (distribution) certificates.
Anyway, so they will need to share a distribution certificate, by sharing the private key (p12 file) of it, as you can find in the answer here.
In our account, it appears as if we can have up to two valid distribution certificates.
We don’t really know how this ultimately worked – we didn’t do it manually over the developer portal, but used xCode for it. Alice generated her certificate, Bob revoked and regenerated, Alice did the same thing – but suddenly they both had a valid distribution certificate, instead of invalidating Bobs certificate.
In the documentation it was mentioned that you can have up to 2 valid distribution certificates. We have also manually tried to generate the distribution certificates and could confirm that it is limited to two.
However, we then got recently invited to a customer’s developer program to sign apps on his behalf.
I assume the customer was not aware that we require the private key from his distribution certificate. We therefore tried to manually generate a distribution certificate, and saw that it was not possible. To our surprise though, the customer managed to generate 3 valid distribution certificates.
Any idea how this worked?
Our questions in a nutshell:
1. What is best practice when you manage a team of developers?
Do you normally share the private key of the first developer who generated the certificate with all other team members, which should be able to sign the app?
2. What is the best practice when you work with clients?
Do you ask them to generate another private key, or is there some hidden functionality to generate as many distribution certificates as you want, given that every developer uses his own account?
3. What happens when we revoke a certificate.
It doesn’t affect the apps in the app store, but only seems to limit other developers to build their app. However, what happens with APNS / Push Server certificates? When we revoke a distribution certificate through xCode, will this also suddenly stop working for the sender?
Thank you for your help.
After a long time of investigation and trying things out, here is what we think is the best fit for us. Not sure if it is best practice but it seems to work for us just fine.
1. What is best practice when you manage a team of developers?
One person generates a distribution certificate using his mac. He then exports the certificate (public AND private key) in a p12 file, as suggested by washloops and shares it with the team.
2. What is the best practice when you work with clients?
We have two sorts of clients:
Clients working with multiple suppliers (so we are just taking care of 1 app, out of their portfolio) - We ask them to share their distribution certificate (public + private key). If they don't have it, they need to get it from another vendor.
Clients working only with us - We generate the certificate and share it with the client later on. This allows them to share it with other vendors if they need to.
3. What happens when we revoke a certificate.
From our tests: "nothing". If you revoke a distribution certificate, it will prevent developers using this certificate from submitting / building apps. However, existing APNS / Push certificates are not affected.
For us it seems as APNS / Push certificates are totally independent, and if you wish to revoke them, you need to revoke both.
You have to create just 1 distribution certificate. After that you go to Keychain Access, select the certificate and export it as ".p12", and maybe add a password to it.
After that you just install it in the other computers.

I have an in-house enterprise app that is managed (deployed) from MaaS360
'https://portal.fiberlink.com'
And this app is built (and still maintained) in XCode 4.6.3 (i know, i know), so I don't have any of the fancy new features in XCode 7 that might help alleviate this problem. In fact, even the refresh button in Organizer no longer works... you tap it and a dialog says "service unavailable" and I've tried it on different days, so it's not just a temporary glitch or service interruption. I believe apple disabled whatever portion of their service was servicing that request from XCode 4's Organizer.
The provisioning profile on it is going to expire in March, and I'm trying to figure out how to renew it without inconveniencing the users by making them download a new rebuilt app. It would be particularly painful for them because it would require they sync a few gigabytes of data from their device through iTunes for each person, and it's a few hundred people.
My problem is, my certificate I used to sign the app is also expiring around the same time (in March).
I happened to have another certificate and an associated provisioning profile, I had generated on a different mac which expires in 2019, and I tried to use it to update the expiring provisioning profile on MaaS360 for this app in question, and I get this error
So what has me a little terrified is, I'm back on the mac where I originally created and deployed the app... if I need to renew my existing certificate (which I assume means revoking it and replacing it with a new one), in order to create a new provisioning profile, aren't I going to run into this dialog again, claiming that my certificates don't match, because I'll now have a new one, hence I can't update the profile.
If the only way to update my expiring provisioning profile is with my soon-to-be-expired-but-also-identical certificate which originally created the profile, that still means my profile is going to expire as scheduled because my original certificate will have expired too.
Is there a way out of this dilemma?
You can have two certificates active at the same time. So I would generate a new certificate using the same key you used to generate the original one. To do this on the Apple developer portal, you will need the cert signing request. Most developers don't save this when they generate their certificate the first time. The good news is, if you have the private key that was used for your distribution certificate, you can use that to generate the CSR. To find out if you have the private key, you can use this post for how to locate it in the Keychain app. https://stackoverflow.com/a/33651921/3708242
Once you have verified that you have the private key used for the certificate for the app store distribution, you can generate the a CSR using the following procedure: https://stackoverflow.com/a/7111454/3708242
Once you have the CSR, go to Apple's developer portal and generate a new distribution certificate for "In-House and Ad Hoc" distribution. As long as you only have one out there, you should be able to create a second without having to revoke the existing one. Once you've done that, you will likely need to provide that certificate to the MaaS360 service (I'm not familiar with how that works, but somehow the Maas360 server must have the private key and certificate that the apps were built with, as it is clearly checking that when you push the build of your app and the certs don't match). So download the new cert and provide that to MaaS360.
Then, generate a new distribution profile using the new certificate. Or you can update the existing one to use the new cert by clicking the edit button on the provisioning profile, then changing the radio button to the new cert which should expire several years out. Note that this won't prevent any existing apps built using the profile from running in the meantime (revoking the certificate, however, would immediately cause the apps to stop working, which you don't want). Save and download the new profile, and use it to rebuild the app.
The app will then be built with the new certificate, that won't expire any time soon. I do think you are missing the part of the process where you will have to provide the new cert to MaaS360. I can't really help you with that part, but hopefully there is some documentation from IBM that can help you out there. But, you will need to fix it, because once the cert expires, non of the apps built with it will work. Good luck and let me know if any of this is not clear enough.
I made an application for a client. He added me as a team member, but without admin/agent rights. In order to upload the application to apple store, I need a distribution provisioning profile, the distribution certificate associated with it, and the key that was used to create the certificate, exported from the mac where it was created. As I know, there is no way to use the distribution provisioning profile without both distribution certificate and the key. The client doesn't want to give me the key but he also doesn't want to give me admin.
There is a 3rd solution, to create my own distribution certificate on his account using a private key from my mac, but I noticed that the maximum number of distribution certificates is 3, and the client already has 3.
I doubt there is any problem security wise for providing my distribution certificate in there. Is there?
I also am not sure if the client should accept my own distribution certificate to be used for uploading the application. Should he?
Also, assuming that all 3 distribution certificates slots are taken and there is no way to obtain a free slot, what should I ask the client to do, in order to assure him that all is safe and good.
Also, is there any other way to upload his application without him giving me admin or key?
If they are touchy about this, which they don't need to be, they could provide you with the cert and its key and, once you have uploaded the app, revoke the cert. meaning you wouldn't be able to do anything with it. They can then just generate a new one as and when they need it.
[I've checked similar posts and my question differs slightly from others in that we have multiple apps signed under one certificate]
We've been commissioned to work on an existing iOS app for a client and now need to distribute it to the app store using their certificate. The problem is that the certificate wasn't generated by us so we do not have the private key (.p12 file). Assuming that we can't get this, I believe the only option is to revoke the existing distribution certificate and create a new one...so my question is:
Q1) The client has 3 existing apps on the app store all signed under this existing Distribution Certificate. If we revoke the existing certificate and create a new one will it break the existing apps?
Q2) Presumably the 'Company' name for your app in the app store is taken from the distribution certificate? i.e. If I signed the app using our certificate instead, would our company name appear above the app instead of the clients?
Thanks!!
Neil
I had this same dilemma.
Q1) It is ok to do this, it will not break the existing apps. Just go ahead and create a new one right after you do it.
Q2) The name will not be affected, you set this yourself in iTunes connect when you submit the app.
This is getting frustrating. I have two identities, one old, one new, and the latter should be used to deploy iOS apps to the App Store.
I've created the new user, granted him admin access, then I created the app name and provisioning profiles. However, in the Organizer I see that the Dev provision works flawlessly, while the Deploy profile shows me the dreaded error:
Valid signing identity not found.
How can it be?
Well, I see that in the Certificates section in the iOS Provisioning Portal, there is only one distribution certificate, the one belonging to my company.
Is there a way to enable the new user to create apps without accessing the uberadmin's Xcode?
Thanks & Cheers!
You need the key that was used to create the Distribution Certificate for your company.
Remember when you created your developer certificate? Then you went to keychain -> certificate assistant -> Request a certificate from ...
When you did this, your Mac paired your certificate request to a key in your keychain. Once your developer certificate was processed and you downloaded it to your computer, it could be accessed by your computer through that key.
But if you did not create the Distribution Certificate that your company has, you don't have the key on your computer.
Take a look at your certificates in keychain:
Go to 'Certificates' and expand your developer certificate - it will have a little key with your name.
Now try to expand your distribution certificate - it will not have a key, right?
If this is the case, you have two options:
Ask the person who created the Distribution Certificate to export it from his keychain. This will create a file that includes both certificate and key.
Delete the current Distribution Certificate, and create a new Certificate Signing Request from your computer, which will connect it to a key that you have.
First method require access to "Uberadmins" computer. The second require admin access to your teams Apple account. There is usually no downside in using method 2, because creating a new certificate is necessary from time to time anyway. It will not affect already published apps, just coming releases and updates need to use a the latest certificate.
Once all this is done, you need to create a distribution provisioning profile for App Store and connect to the Distribution Certificate that you are going to use. (if you went with option 1, you might already have done this).
Download the profile to your computer, install it, and then in your app, select to build with this profile for distribution builds.
According to Apple's documentation:
A team’s distribution certificate allows a developer to build an app for distribution. If your team wants to use another Mac to create a distribution build, you need to transfer a copy of the distribution certificate as described in, “Safeguarding and Transferring Your Signing and Provisioning Assets” in Tools Workflow Guide for iOS. (from Managing a Distribution Certificate)
So, in order to have multiple users able to create & submit App Store builds, you must share a private key between them.
Create a new private key for the team, and then send that private key to everyone who needs it. Follow the instructions under Generating a Certificate Signing Request with Keychain Access.
