Keybase SMS Verification

By completing Keybase SMS verification with a virtual number, you can sign up for this end-to-end encrypted secure messaging network without exposing your personal phone number.

Keybase is a security platform built on public-key cryptography, offering end-to-end encrypted messaging, file sharing, encrypted storage and team tools; it was acquired by Zoom in 2020. Phone verification is requested to strengthen account security, make contact discovery easier and prevent automatically generated fake accounts from flooding the service.

When the sign-up screen asks for a phone number, you pick a virtual number for Keybase from the panel, enter the incoming SMS code in the relevant field and complete verification. It is a fast, practical method for anyone who wants to keep their real line private, try the platform without tying it to a personal number, or open a second account under a separate identity.

Although Keybase is a privacy-focused tool, security is largely in your hands; choose a strong, unique password and keep your recovery keys (paper key) stored offline in a safe place. A virtual number is only for one-time codes; since you may not keep permanent access to that number, don't entrust your account solely to a phone-based recovery method, and pair more than one device with your account where possible.
