Free phone and 2FA tools

Small, private tools for anyone dealing with phone numbers and two-factor authentication. They run in your browser, so nothing you type is sent to Ucode.

Phone number checker

Check if a phone number is valid and whether it is mobile, landline or VoIP. Runs in your browser.

2FA code generator

Turn a 2FA secret key into the current 6-digit TOTP code, like Google Authenticator. Runs in your browser.
