Popular messaging app, WhatsApp has added fingerprint lock to secure unwanted access to the platform.
You can now require a fingerprint to unlock WhatsApp using the process below:
Tap Settings > Account > Privacy > Fingerprint lock and enable Unlock with fingerprint.
You can then choose to unlock immediately or after 1 minute or 30 minutes.
This is an additional feature to the two-step authentication method introduced earlier which blocks unwanted access to your WhatsApp account.
