Devise - "forgot password" function - Username and Password not accepted - ruby-on-rails

I am trying to set up the "forgot password" function that comes with devise. I am using rails 5. It always gives me the error: "535-5.7.8 Username and Password not accepted"(Net::SMTPAuthenticationError in Users::PasswordsController#create though.
My code looks like this:
In development.rb I added:
config.action_mailer.default_url_options = { host: 'localhost', port:3000 }
config.action_mailer.delivery_method = :smtp
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
config.action_mailer.default :charset => "utf-8"
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:authentication => :plain,
:domain => 'gmail.com',
:user_name => 'xyz#gmail.com',
:password => 'abcde',
}
Under config > initialisers > devise.rb I added:
config.mailer_sender = "xyz#gmail.com"
and under config > environment.rb:
ActionMailer::Base.delivery_method = :smtp
Am I missing anything or did I do something wrong?
Also another question: I need to link it to my personal account (i.e. replace the user_name and password with the details of a real email account), there is no default devise account the emails get sent from, right? I'm just wondering because like this everyone in my team would be able to see the password of the mail account we're using, right?
Any advice would be highly appreciated! Thanks in advance.


SMTPAuthenticationError is an error at the SMTP authentication layer.
This means that whatever SMTP service you're trying to use is reporting back some kind of authentication issue.
I do not use Gmail as my SMP, but this error seems strange to me as it says Username and Password not accepted, which is different from incorrect.
Further research shows that Gmail no longer accepts less secure SMTP requests.
Google now doesn't accept login from less secure apps. So you need to go to https://myaccount.google.com/security scroll to the bottom and turn ON "Allow less secure apps: ON". Now when you add the SMTP details to "Send as" google will accept them. You need to do this for the email ID you are adding in your Send as section.


I think it's related with your gmail settings. If you see errors like Net::SMTPAuthenticationError while using gmail for sending out emails, visit your gmail settings and enable less secure apps:
"MyAccount" > "Sign-in & security" > "Connected apps & sites" > "Allow less secure apps"


Go to your google email account setting and change this settings. and try more than 1 times.

Net::SMTPAuthenticationError Rails Mailer Doesn't work with new email address?

It worked for my other Gmail account 5 minutes ago so I know my config is all correct but now I'm getting an authentication error. I just made a new Gmail account and changed the username and password in my development.rb file and now it doesn't work.
config.action_mailer.default_url_options = { host: "locahost:3000" }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:enable_starttls_auto => true,
:user_name => ENV['gmail_username'],
:password => ENV['gmail_password'],
:domain => 'localhost',
:authentication => :plain
}
This thread helped me last time but like I said I don't know what else to try..? Net::SMTPAuthenticationError when sending email from Rails app (on staging environment)
For my new Gmail account two-factor authentication is OFF, I turned ON the setting to allow less secure apps as I had to for my other account. AND I also went here https://accounts.google.com/DisplayUnlockCaptcha and allowed account access. Not sure what I missed...Probably something stupid.

If two-factor authentication is ON go to the app passwords section, then in the first select choose "Other (custom name)", enter the name of your application and click "generate". After that you get a pop-up with the password you have to use in your action mailer settings.
*if two-factor authentication is OFF, enable it first.

G-suite email settings not worked while sending email in rails

I used G-suite email setting for sending emails from Rails application. This is my client G-suite email. Generally I used my gmail settings and it's work but G-suite email settings not work. Below code:
config.action_mailer.smtp_settings = {
:address => "smtp-relay.gmail.com",
:port => 587,
:user_name => "info#XXXX.com",
:password => "XXXXXX",
:authentication => "plain",
:domain => "gmail.com",
:enable_starttls_auto => true
}
I used address: "smtp.gmail.com" as well but not working.
I got error: SMTP: authentication failed and sometimes nothing but not received email.
Anyone have idea or same experience solutions.
Thanks

there is this configuration in gmail that COULD be the cause of the problem. I am not sure it would result with an error: SMTP: authentication failed
this is the guide to allow the unsafe apps
Change your settings to allow less secure apps into your account.
We don't recommend this option because it can make it easier for someone to break into your account. If you want to allow access anyway, follow these steps:
Go to the "Less secure apps" section of my Account.
Turn on Allow less secure apps. (Note: If your administrator has locked less secure app account access, this setting is hidden.)
also I found similar post for this problem, for example a similar issue was solved in this so question

These settings worked for me:
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.perform_caching = false
config.action_mailer.delivery_method = :smtp
# SMTP settings for gmail
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => 'info#example.com', # Change this to the email you're sending from
:password => 'your_password_goes_here', # Change this to your password
:authentication => "plain",
:enable_starttls_auto => true
}
One extra tip. By default: config.action_mailer.raise_delivery_errors = false set to true so you can see any error messages in your browser/console
NOTE: in order for the mailer to work with any google email account you must have 'Allow less secure apps' turned on.
To do this, first go to the G-Suite admin console and turn on Security -> Advanced Security Settings and check the radio button: "Allow users to manage their access to less secure apps"
Now login to your G-Suite user account, go to My Account -> Sign-in & security. At the bottom you'll see Allow less secure apps. Turn that on.
You're good to go!

Configuring production.rb file to send emails with Rails 4

I am stuck with sending emails in Rails. I need to send password reset or activation account emails using Devise gem. Thanks Devise has email sending functionality builtin. I only need to configure sender. I have googled and found many tutorials on how to do that. Here are the things I still don't understand as many tutorials do not talk about them much:
Any tutorial comes with something like that:
config.action_mailer.default_url_options = { :host => 'gmail.com' }
config.active_support.deprecation = :notify
config.action_mailer.delivery_method = :smtp
config.action_mailer.raise_delivery_errors = false
config.action_mailer.default :charset => "utf-8"
# SMTP settings
ActionMailer::Base.smtp_settings = {
:port => 587,
:address => 'smtp.gmail.com',
:domain => 'gmail.com',
:user_name => ENV['username'],
:password => ENV['password'],
:authentication => :plain,
}
So unclear things for me are:
1) what is :host, can I use localhost?, in example it is gmail.com. Do I need to set up some gmail server or whatever.
2) what is :domain, again is it my site domain? or using just gmail.com is fine?
3) What is user_name and password?
So the general question is do I need to install some server for mail on my production server and so on, people on this tutorials skip this part. Who sends my email? Rails app server? or separate smtp server?

1) host is a variable used to generate links to your site in the email (see comment).
2) domain is the sending domain of the email, if you have your own domain you could put your domain there.
3) user name and password are the credentials of your gmail account (or the account that you send mails from). If you have your own smtp relay server set up you can use information for that.
This will likely only work for a minimal number of emails sent, you need to look into a professional service that delivers your emails if you intend on sending more than about 100 per month.

Net::SMTPAuthenticationError when sending email from Rails app (on staging environment)

I am sending email from my Rails application. It works well on development environment, but fails on staging. I get the following error:
Net::SMTPAuthenticationError (534-5.7.14 <https://accounts.google.com/ContinueSignIn?plt=AKgnsbtdF0yjrQccTO2D_6)
Note, that my I don't have a domain name for my staging.
Here are my settings in staging.rb
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => "my.ip.addr.here:80" }
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'my.ip.addr.here:80'
:user_name => "my_email_name#gmail.com",
:password => "my_email_password",
:authentication => 'login'
}
Please, help.
Edit.
After adding :tls => true option I get
OpenSSL::SSL::SSLError (Unrecognized SSL message, plaintext connection?)
And then I changed port to 25 and now I get this (with 30 seconds delay):
Timeout::Error (execution expired)

I had the same problem: emails were sent from development, but not from production (where I was getting Net::SMTPAuthenticationError).
This drove me to conclusion that the problem was not with my app's configuration, but with Google.
Reason: Google was blocking access from unknown location (app in production)
Solution: Go to http://www.google.com/accounts/DisplayUnlockCaptcha and click continue (this will grant access for 10 minutes for registering new apps).
After this my app in production started sending emails ;)

Solved!
I simply changed password for my gmail account and somehow errors disappeared.
After dozen of changes, the final settings I ended up with are:
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => "my.ip.addr.here" }
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'my.ip.addr.here:80',
:user_name => "my_email_name#gmail.com",
:password => "my_email_password",
:authentication => :plain,
:enable_starttls_auto => true
}

This solution is working for me:
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host:'localhost', port: '3000' }
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'localhost:3000',
:user_name => "xyz#gmail.com",
:password => "password",
:authentication => :plain,
:enable_starttls_auto => true
}
It's true that Google will block your sign-in attempt but
You can change your settings at https://www.google.com/settings/security/lesssecureapps so that your account is no longer protected by modern security standards.

go to following link and turn on
https://www.google.com/settings/security/lesssecureapps

The above solution provided the correct settings (which I already had) but did not solve the issue. After continued attempts, I kept getting the same error. Turns out, I had to "clear the CAPTCHA" from the web. See the gmail documentation for details.
You can also jump right to the "clear the CAPTCHA" page here.

I had the same problem.
Solution:
You can turn on less secure apps option (at here).
https://myaccount.google.com/lesssecureapps
And unlock Captcha (link):
https://accounts.google.com/DisplayUnlockCaptcha

A lot later but just in case it helps anyone.. Just called Google Apps Help Center and they instructed to change the lesssecureapps setting (as everyone else) but also to change the port to 465.
In my case, that did the trick!

To resolve this issue:
If you see: Net::SMTPAuthenticationError (535-5.7.8 Username and Password not accepted.), then you need to allow less secure apps to login your google account.
To enable less secure apps login follow: https://myaccount.google.com/lesssecureapps?. But will allow all apps to login.
If you want to customize it refer : https://support.google.com/a/answer/6260879?hl=en
Then may be possible you will get Net::SMTPAuthenticationError (534-5.7.14), so to resolve this refer: pli=1http://www.google.com/accounts/DisplayUnlockCaptcha. After that click the continue from the page you get redirected. It will verify your Captcha and your app will get verified to use your google account to send emails.
NOTE: Please make sure you'r using correct credentials of your gmail account.
If you'r not willing to allow all the apps please refer: https://support.google.com/a/answer/6260879?hl=en. From the link go to Use alternatives to less secure apps, this will guide you to an alternative way to Allow Less Secure apps access to your google account.

The accepted answer seems very old, I don't know if at that time the followin (better) solution was existing:
Go to https://myaccount.google.com/u/0/apppasswords
Generate a new password for you app
Replace the personal password with the generated password in config.action_mailer.smtp_settings
Now, sending emails works perfectly!

Hello this also worked for me and so if someone is still having a problem try this out.
Make sure you have figaro in your gemfile.
To save sensitive information such as username and password as environment variables
gem 'figaro'
And in your config/environments/development.rb , paste the codes below
using smtp as method delivery
config.action_mailer.delivery_method = :smtp
SMTP settings for gmail
config.action_mailer.smtp_settings =
{
:address=> "smtp.gmail.com",
:port => 587,
:user_name => ENV['gmail_username'],
:password=> ENV['gmail_password'],
:authentication=> "plain",
:enable_starttls_auto=>true
}
config.action_mailer.default_url_options = { host: "locahost:3000" }
In your config directory create a file called application.yml
and add the codes below.
gmail_username: 'example#gmail.com'
gmail_password: "your_example_email_password_here"
You must use your email and password for authentication in the file.

I also faced the problem, and after some research in Gmail setting, I found the solution:
In gmail, go to settings.
Select "Forwarding and POP/IMAP" tab.
In the IMAP access section, select "Enable IMAP".

I had the same problem and after some trial and errors, have come to this resolution which is an option to be enabled in google:
Click https://www.google.com/settings/u/0/security/lesssecureapps
Enable 'Access for less secure apps' here by logging in with the email address you have provided in smtp configuration.

Error when sending email confirmation using ActionMailer on ROR

I am developing a website using ROR on Windows 7 (64-bit). I am trying to setup my website so that a person who creates a new login on it gets a confirmation email. I am using ActionMailer for the email confirmation sending. I am trying to configure it to send confirmation email using Gmail SMTP server. (This is just for testing. Once it works, I can use something else on the deployment server.)
I am getting this error:
Application-specific password required
Here is the code snippet from development.rb:
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
# these options are only needed if you choose smtp delivery
config.action_mailer.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:domain => 'gmail.com',
:authentication => :login,
:user_name => 'my_login#gmail.com',
:password => 'my_application_specific_password'
}
Why I am getting this error even though I generated a new application-specific password for this purpose and am using it? How to fix this?

I think you may have enabled extra 2-step security on the Google Account you are using to send emails. This can require you to sign in using a special code sent to your mobile phone by text message; or for particular non-compatible applications, creating an 'Application-specific password'.
More details on Application-specific passwords here.
