[Auth] I couldn't login

[universish]

When logging in to ente auth, it wrote that it could not open the password, that the password was too long, that the device was not enough to open the password, that I needed to change the password, that I could make the new password the same as the old password if I wished; it would not log in. I changed the password, saved the old long password again, and this time it logged in.
Am I having this problem because my device is Android 6.0.1?
