How to sync KeePassium with OneDrive


  1. Install OneDrive app and login into your account
  2. Open KeePassium, tap the top-right + button, then Open Database
  3. Select “OneDrive” in the Locations list (if you don’t see it in the list, make OneDrive visible)
  4. Select your database file
  5. That’s it!


OneDrive is restricted by corporate IT policies

This is the root cause for most of OneDrive-related issues. It applies when you have the Microsoft Intune app installed, or a OneDrive for Business account added to your OneDrive app. (Even if the database itself is stored in a personal OneDrive account.)

Personal and business accounts

Corporate restrictions apply to the whole OneDrive app. So if you have both a business and a personal OneDrive account, they both will be affected by the corporate limitations.

There are three possible workarounds:

  • Ask your IT department to whitelist KeePassium for accessing files in OneDrive.
  • Connect to your OneDrive account via third-party apps like Boxcryptor (free), FE FileExplorer Pro (paid) or FileBroswer (paid). They won’t be affected by the restrictions set for the OneDrive app. Installing them, however, might be against the corporate policies as well.
  • Move your database to another cloud, such as iCloud Drive, Dropbox, or any other supported sync location.

OneDrive is not listed as a storage location

There are two possibilities:

  • It might be hidden. Press the More button in the file selection dialog, then Edit, and make sure that OneDrive is turned on.
  • If OneDrive is still missing from the list above, the OneDrive app might be restricted by your company’s IT policies.

Cannot select file in OneDrive

OneDrive folder shows “Content not available” (“Inhalt nicht verfügbar”)
Reinstall OneDrive app, then re-add your databases to KeePassium.
When you select a file, it seems to disappear
When you try to add a database from OneDrive, the file seems to disappear when you tap it. No worries, the database is still there — but your corporate IT policy does not allow accessing it from other apps, such as KeePassium. See above for possible solutions.
When you select a file, nothing happens
When you try to add a database from OneDrive, nothing happens when you select the file. The file selection dialog simply remains on the screen. This is also caused by the corporate restrictions on OneDrive app.

The requested operation couldn’t be completed because the feature is not supported

This error can happen either due to corporate restrictions or due to a random system glitch. Try to restart your device and see if this resolves the issue.

Unrecognized database format

This is a clear sign of corporate IT restrictions. OneDrive app is not allowed to provide files to “unapproved” third-party apps like KeePassium. However, instead of returning a suitably worded error, OneDrive returns wrong file content. (There’s more detail on Reddit.)

OneDrive sync stopped working after iOS update

iOS updates seem to affect offline caching in OneDrive. As a result, a perfectly working KeePassium starts freezing when trying to access a database in OneDrive.

To fix this, open device settings, scroll down and select OneDrive. Then, toggle the Clear Account Settings switch. This will clear the cache and reset your installation of OneDrive. You will need to login to OneDrive again, and re-add your database to KeePassium.

SharePoint site not listed

If you see your SharePoint sites in the OneDrive app, but not in KeePassium’s file selection dialog — make sure to follow the specific SharePoint site. This will make the site available in all apps.
