Summary
LastPass Authenticator is an authentication app that provides two-factor login security for LastPass accounts and other supported services. It generates six-digit codes refreshing every 30 seconds and supports one-tap approval via push notifications, with accounts added automatically by scanning a QR code. Encrypted backup lets tokens be restored on a new or reinstalled device, and SMS codes serve as an alternative login method. Trusted devices skip repeated code requests, and the app also works with other TOTP-compatible services, including those supporting Google Authenticator.
