I have the same problem too.

1. I logged in as admin
2. I created a user and a new password was generated for this user, which I copied
3. I have logged out
4. I logged in with this new user and using the saved password.
5. Projeqtor keeps asking me for the new password and to validate it, the green message "valid password strength" appears; I press the Login button
6. I always find myself at the same screen and don't go forward.
7. I can't even open the main page yet to be able to login with Admin because it keeps asking me for a new password.

I am forced to login as admin in another browser or ask what I am using.

This issue is fixed.
The fix is proposed on the forum.
We"ll soon deploy a patch with the fix
