WhatsApp introduced fingerprint lock on supported Android devices on Thursday to help users stop hackers or others from monitoring their chats.
Earlier this year, the company said, it rolled out Touch ID and Face ID for iPhone users to provide an extra layer of security for WhatsApp users. “Today we’re introducing similar authentication, allowing you to unlock the app with your fingerprint, on supported Android phones,” the company said in a statement.
To turn the feature on in the app, tap Settings > Account > Privacy > Fingerprint lock > Unlock with fingerprint. Turn on Unlock with fingerprint, and confirm your fingerprint. You can set the app to lock immediately, or after one or 30 minutes.
