WhatsApp has started rolling out several new account security features, including support for multiple passkeys and stronger two-step verification.

While the instant messaging service already allowed users to add passkeys for secure logins via fingerprint, Face ID, or screen lock code, it now lets them create separate ones for each platform.

"More than a billion people have already set one up, and you can now add more than one passkey to your account if you use both Android and iOS devices. To get started, go to Settings > Account > Passkeys," it said.

WhatsApp has also updated its two-step verification security feature to allow alphanumeric passwords instead of six-digit PINs.

"Until now it was a six-digit PIN, we've now upgraded it to a full password: longer, alphanumeric, and even with special ch@racters to make it harder to guess. If you've been using '123456,' this is your sign to upgrade," WhatsApp added.
