It is faster, but not a replacement for good password hygiene
Biometric login speeds up daily access, but your account still relies on the underlying password for backup access and account recovery, so it is still worth keeping that password strong and private.
Turn it off on a shared or borrowed device
If you ever log into your banking app on a device that is not exclusively yours, disable biometric login there afterward so someone else's registered fingerprint or face cannot be used to access your account later.
Frequently Asked Questions
Is biometric login less secure than a password?
Generally considered comparably secure or more so for everyday use, since a fingerprint or face is harder to guess or steal remotely than a password, though it depends on your device's own security implementation.
What happens to my registered fingerprint if I sell my old phone?
Resetting the phone to factory settings before selling it clears locally stored biometric data, and it is good practice to also remove the banking app's biometric login manually beforehand as an extra precaution.
