Umbraco External Membership Provider - umbraco

Question

Current Umbraco Version - Umbraco version 7.5.3
We have an Umbraco Project that uses a Custom Membership Provider to authenticate members (front-end) to certain protected page(s). This membership provider has worked fine until we had to upgrade the system that our members are authenticated via. After upgrading the external system our Membership Provider now has a strange issue that I'm struggling to resolve. The issue is as follows:
1 - User attempts to login with their correct details (via Umbraco Login Form) and receives an 'Incorrect Username & Password Error'
2 - User then uses our 'Reset Password' functionality, which sends them a 'PIN' that they enter into an Umbraco Form. If the PIN matches, they're then presented with a Form to enter a new Password.
3 - The user is now able to log via the newly created Username & Password (into Umbraco Protected Areas).
4 - Now, the user goes to our External system and enters their username and password (created via the Umbraco Form). This also logs them in successfully. (This seems to change the password of the user?)
5 - User now tries to re-login to Umbraco Protected Page but again receives an incorrect Username & Password.
6 - However the Username and Password still works on the external system.
After some research we have come to the conclusion that our external system now seems to use a different Encryption method that Umbraco isn't compatible with?
I'm really struggling to figure out how/why this is now happening and what I need to change to ensure that the passwords both match and that the members can access the protected pages.
Here is what I believe is running the Login/Password Reset Logic:
namespace Profile.Controllers
{
[PluginController("Profile")]
public class SecurityController : SurfaceController
{
public string RandomString(int length)
{
var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
var stringChars = new char[length];
var random = new Random();
for (int i = 0; i < stringChars.Length; i++)
{
stringChars[i] = chars[random.Next(chars.Length)];
}
return new String(stringChars);
}

Answer 1

Resolved.
Just needed to add:
hashAlgorithmType="SHA256"
Into Web Config.
