The Authy mobile apps for iOS and Android both have an App Protection feature to help keep your 2FA accounts safe. Once enabled, App Protection will request a 4-digit PIN code or biometric check (fingerprint, Touch ID, or Face ID on supported devices) whenever the Authy mobile app is opened.

Alert: The App Protection PIN (and optional biometric data) is never stored in our servers. Make sure you write it down somewhere safe or use a PIN that only you know. If you ever forget your PIN, any 2FA account tokens that have not been backed up will be permanently lost. Users can, however, recover their Authy account by following the process here: Reinstalling Authy and Restoring Access to your Account.
