How to sync using Nextcloud
This guide explains how to sync KeePassium database with other devices using Nextcloud server.
KeePassium supports two synchronization methods for Nextcloud:
- Direct connection via WebDAV — more reliable
- Integration with iOS Files app — easier to set up
Method 1: Direct connection via WebDAV
With this approach, KeePassium would communicate directly with your Nextcloud server, using WebDAV protocol.
- Find your server URL address. Its typical format is
https://cloud.SERVER.com/remote.php/dav/files/USERNAME - Follow the direct WebDAV connection setup guide
For more info, refer to Nextcloud documentation: (Accessing Nextcloud files using WebDAV](https://docs.nextcloud.com/server/latest/user_manual/en/files/access_webdav.html)
Method 2: Integration with iOS Files app
- Install Nextcloud app and log in to your account
- Open KeePassium, go to Databases screen (tap < Back if necessary)
- Tap + → Open Database
- If Nextcloud is not visible in the list, make it visible
- Select your database file
Troubleshooting
Unfortunately, Nextcloud's integration with iOS Files app is quite fragile.
- Sometimes Nextcloud does not download files changed on other computers until you open the Nextcloud app. This is a Nextcloud issue, known since 2017. Until Nextcloud fixes these issues, please make sure to sync by opening the Nextcloud app.
- If you edit your database elsewhere, then edit it in KeePassium (without opening the Nextcloud app first), the first change might be overwritten.
- Sometimes, Nextcloud app shows that the file is updated, but KeePassium keeps opening an old cached copy. In this case, the solution is to clear Nextcloud cache (Nextcloud app → More → Settings → Advanced → Clear cache).
As a more reliable alternative, we suggest the direct connection via WebDAV instead of the native Nextcloud app.
