Protect your online accounts with simple and secure two-factor authentication. Auth Code makes it easy to generate 2FA verification codes for your online accounts. Add an account by scanning a QR code or entering a setup key manually, then access your one-time codes whenever you need to sign in. KEY FEATURES ⢠2FA Authentication Generate time-based one-time passwords (TOTP) for services that support authenticator apps. ⢠Quick QR Code Setup Scan a QR code to add an account in seconds. ⢠Manual Setup Add accounts using a secret setup key when QR scanning is unavailable. ⢠Fast Verification Codes Access your authentication codes quickly whenever you sign in. ⢠Multiple Accounts Keep your authentication accounts organized in one convenient place. ⢠Privacy & Security Your authentication data is protected on your device. HOW IT WORKS 1. Enable two-factor authentication on a supported website or service. 2. Scan the provided QR code with Auth Code. 3. Enter the generated verification code to complete setup. 4. Use your new 2FA code whenever you sign in. Two-factor authentication adds an additional layer of protection beyond your password and helps keep your online accounts more secure. Auth Code works with services that support standard authenticator-based two-factor authentication.
