Yes. A 6-digit PIN has 100 times more possible combinations than a 4-digit PIN, making it significantly harder to guess or brute-force.
Can I use this for Google Authenticator backup codes?
Google Authenticator generates its own time-based codes. However, you can use this generator to create backup codes or recovery PINs that you store securely.
