Not sure who's really on the other end? Verify them in seconds.

LastID lets you confirm the identity of anyone you're talking to: on any call, text, or message with one tap. No callbacks. No guessing. No wondering if someone is who they say they are.

HOW IT WORKS

Someone contacts you and you want to be sure it's really them.
Tap "Verify" and send a challenge.
They confirm their identity using cryptographic proof on their device.
You get instant confirmation. Done.

It works the other way too. When someone needs to verify you, respond to their challenge and prove it's really you. Both sides. Seconds.

WHEN YOU'LL USE IT

A colleague calls from an unfamiliar number
Someone asks you to act on something urgent
A contact reaches out on a new channel
You need to confirm someone's identity before sharing sensitive information
Anyone you're speaking with needs to verify you
