Firebase Authentication: Password must contain capital letter

Question

My application is linked with firebase database and authentication.

When a user creates an account, the only requirements for the password are for it to be 6 charact

Answer 1

There is no way to configure Firebase Authentication's rules for password strength.

• Firebase Password Validation allowed regex.

You can (and should ) restrict it from your code. But you can't prevent malicious users from bypassing this by calling the API directly.

If the password strength is a hard requirement for your app, consider implementing custom authentication. This example of custom username (instead of email) and password authentication might be helpful.
