-# FAQ
-
-## General
-
-### How can I contribute?
-
-There are lots of ways! Please refer to our [contributing
-guide](https://github.com/beemdevelopment/Aegis/blob/master/CONTRIBUTING.md).
-
-### Why is the latest version not on F-Droid yet?
-
-We don't release new versions of Aegis on F-Droid ourselves. Once we've released
-a new version on GitHub, F-Droid will usually kick off their automatic build
-process a day later and publish the app to their repository a couple of days
-afterwards. It can sometimes take up to a week for a new version to appear on
-F-Droid.
-
-### Can you port Aegis to iOS/Windows/MacOS/Browser Extension?
-
-We don't have plans to port Aegis to other platforms.
-
-### Can you add support for Autofill?
-
-On Android, only one app can be active in the Autofill slot at a time, and since
-this is typically occupied by the password manager, we don't see much value in
-adding support for this feature in Aegis.
-
-### What is the difference between exporting and backing up?
-
-Exporting is done manually and backups are done automatically. The format of the
-vault file is exactly the same for both.
-
-## Security
-
-### I can no longer use biometrics to unlock the app. What should I do?
-
-If you could previously unlock Aegis with biometrics, but suddenly can't do so
-anymore, this is probably caused by a change made to the security settings of
-your device. The app will tell you when this happened in most cases. To resolve
-this, unlock the app with your password, disable biometric unlock in the
-settings of Aegis and re-enable it.
-
-### Why does Aegis keep prompting me for my password, even though I have enabled biometric authentication?
-
-You're probably encountering the password reminder. Try entering your password
-to unlock the vault once. After that, Aegis will prompt for biometrics by
-default again until it's time for another password reminder.
-
-Since forgetting your password will result in loss of access to the contents of
-the vault, __we do NOT recommend disabling the password reminder__.
-
-### Aegis uses SHA1 for most/all of my tokens. Isn't that insecure?
-
-The hash algorithm is imposed by the service you're setting up 2FA for (e.g.
-Google, Facebook, GitHub, etc). There is nothing we can do about that. If we
-were to change this on Aegis' end, the tokens would stop working. Furthermore,
-when using SHA1 in an HMAC calculation, the currently known issues in SHA1 are
-not of concern.
-
-### Why doesn't Aegis support biometric unlock for my device, even though it works with other apps?
-
-The reason for this is pretty technical. In short, since you're not entering
-your password when using biometric unlock, Aegis needs some other way to decrypt
-the vault. For this purpose, we generate and use a key in the Android Keystore,
-telling it to only allow us to use that key if the user authenticates using
-their biometrics first. Some devices have buggy implementations of this feature,
-resulting in the error displayed to you by Aegis in an error dialog.
-
-If biometrics works with other apps, but not with Aegis, that means those other
-apps probably perform a weaker form of biometric authentication.
-
-## Backups
-
-### How can I back up my Aegis vault to the cloud automatically?
-
-Aegis can only automatically back up to the cloud if the app of your cloud
-provider is installed on your device and fully participates in the Android
-Storage Access Framework. Aegis doesn't have access to the internet and we don't
-have plans to change this, so adding support for specific cloud providers in the
-app is not possible.
-
-Cloud providers currently known to be supported:
-- Nextcloud
-
-Another common setup is to configure Aegis to back up to a folder on local
-storage of your device and then have a separate app (like
-[Syncthing](https://syncthing.net/)) sync that folder anywhere you want.
-
-## Encrypted Backups
-
-### Why do I not get prompted to enter an encryption password when exporting?
-
-Aegis uses the same password you have configured to encrypt your vault as the
-password which is used when exporting and importing your vault; so when prompted, 
-you will enter that when importing your vault.
-
-## Importing
-
-### When importing from Authenticator Plus, an error is shown claiming that Accounts.txt is missing
-
-Make sure you supply an Authenticator Plus export file obtained through
-__Settings -> Backup & Restore -> Export as Text and HTML__. The ``.db`` format
-is not supported.
-
-If it still doesn't work, please report the issue to us. As a temporary
-workaround, you can try extracting the ZIP archive on a computer, recreating it
-without a password and then importing that into Aegis. Another option is
-extracting the ZIP archive on a computer and importing the resulting
-Accounts.txt file into Aegis with the "Plain text" import option.
