2FAS vs Ente Auth Comparison

2FAS keeps the secrets on your phone and has no copy of them. On Android the app's database is encrypted with a random key protected by the phone's keystore. On iPhone, according to the app's public source code, its own encryption of stored secrets uses a key built into the app, so the protection there comes from the phone itself and its passcode. If you turn on the Android Google Drive backup without a backup password, Google stores a readable copy. A PIN or biometric lock for the app is optional.

On the device, the codes are encrypted with a key kept in the system's secure storage. With an Ente account, the app encrypts every code before upload with keys that, by Ente's documentation, only your password or recovery key can unlock, so Ente's servers hold only encrypted copies. That is Ente's statement: an outside audit has checked Ente's server, not the Auth apps.

Not encrypted on Android unless you set a backup password; encrypted on iPhone. The backup is off until you turn it on; the Android app reminds you on its home screen. On Android the copy goes to a hidden folder of your Google Drive and Google can read it if you set no password. On iPhone the copy goes to iCloud, encrypted by the app with a random key kept in your iCloud Keychain, or with a key made from your own password if you set one.

The first screen offers Sign up and Log in, with Use without backups as a smaller option below them. With an account, an encrypted copy syncs to Ente. Without one, codes stay on that device only; automatic daily backup files, protected by a password you set, are off until you switch them on. Ente says device transfers and system backups do not count as a backup for offline codes.

2FAS has no accounts of its own. The optional cloud backup uses your Google account on Android and your Apple account on iPhone.

An Ente account, which needs an email address and a password, is used only for the encrypted copy and sync. Without it the app works offline; the desktop apps and the Android app downloaded from GitHub may still contact Ente to check for updates.

The app is published by Two Factor Authentication Service, Inc., which gives an address in Henderson, Nevada. Its licence agreement for the app is governed by the laws of Delaware, with disputes going to Delaware courts or arbitration.

Ente Technologies, Inc. has been a US corporation since 2022; its terms are governed by Delaware law, with a notice address in Dover, Delaware. Ente's privacy policy says its servers and hosting partners are in Europe and that personal information may be accessed from or transferred to the US.

2FAS says the company was founded in 2015 and its team works fully remotely. It also makes 2FAS Pass, a password manager with a paid plan.

Ente was started in 2020 by its founders and says it is funded by customer subscriptions, not venture capital. Since July 2026 it publishes its revenue and customer counts.

2FAS Auth is free and has no ads. The company takes donations through PayPal and says they go to app development; it also sells a yearly plan of its separate password manager.

Auth earns no money of its own. Ente pays for it from subscriptions to its photo storage service and asks people who want to support Auth to subscribe there; at launch in 2022 it said existing users would keep Auth for free if it ever became paid.
