What the App Never Does¶
A short list of promises, and an honest list of what no app can promise.
Private Authenticator never…¶
- sends your setup keys or codes anywhere. Not to Pebble IT, not to anyone. The only copies outside your iPhone are the ones you choose to make: iCloud Keychain sync, backups, exports and the Apple Watch.
- keeps your recovery key. It's shown once while you make a backup, then forgotten. Nobody can recover it.
- shows a code without Face ID or Touch ID.
- looks at your photos. When you save a backup to Photos, iOS grants the app permission to add pictures only, so it can't see your library. When you pick a screenshot or backup images, iOS shows you the picker and hands over only what you chose.
- uses the camera for anything but scanning a QR code on the screen you're looking at.
- collects analytics, shows adverts, or asks you to create an account.
- connects to the internet, except to open two websites in your browser when you tap their links: the Pebble IT website and this documentation.
- deletes an account by itself. Only you can, with Delete All Data, after Face ID or Touch ID.
The permissions it asks for¶
| Permission | When | Why |
|---|---|---|
| Camera | The first time you scan a QR code | To read the QR code |
| Add to Photos | The first time you save a backup to Photos | To save the backup images; it can't see anything else |
| Face ID or Touch ID | The first time you open a code | To confirm it's you |
Everything else, such as the Files picker and the photo picker, is provided by iOS and needs no permission of its own.
What no app can promise¶
- If your phone is unlocked and the launch lock is off, whoever holds it can see your account names (not the codes).
- If your phone is jailbroken or otherwise compromised, software running on it can read what the app reads. The Keychain and Face ID protect a normal iPhone.
- A backup is as safe as its key. Anyone who has both the images and the key can restore your accounts.
- A code on screen is a code on screen. If you read it out, screenshot it, or type it into a fake website, the app can't help.
- The websites you sign in to have their own weaknesses. Two-step verification makes your accounts much harder to steal; it doesn't make the website itself secure.
