The sign in codes your bank, email and games ask for, with nothing hidden. Free to use, codes that are never locked behind a payment, and a one time Pro upgrade for unlimited accounts and iCloud backup. No weekly subscription, no ads, no tracking.
Some authenticator apps charge $9.99 a week, and some lock your codes until you pay. Plain Auth never will.
Every code shows and copies whether or not you ever pay. Being locked out of your own accounts is never a sales tactic here.
Export your accounts from Google Authenticator and scan its transfer code once. Every account comes across, names and all.
Move accounts shows each setup code, after Face ID, so another app or device can scan it. Your accounts are never trapped.
Setup keys live in the iOS keychain. No account, no servers of ours, no analytics. Copied codes clear from the clipboard after a minute.
Optional Face ID or passcode lock, and codes are hidden in the app switcher.
Free keeps up to 5 accounts. Pro is a single $4.99 payment for unlimited accounts and iCloud backup and sync. It is never a subscription.
