There is a breached password engine that we align with for security purposes, which scans user passwords during the sign-up and login process.
It then compares these to databases of known breached passwords (this is all done without exposing passwords).
If a match is found, appropriate actions can be taken, such as requiring the user to reset their password or implementing additional security measures.
So, in essence, you need to choose a password that is more complex and then, the app should allow you to successfully set a new password.
