Explanation of the error message

[Klaus Heim]

Dear Support,

I use Enpass on Mac and iOS. My vaults are synchronized via WebDAV. Recently, I received the following error message:
“Synchronization error. Password required for data on WebDAV.”
Which password is meant here? The vault password or the password for accessing the WebDAV account? Regardless, I am 100% sure that neither password has been changed.

Regards, Klaus

The message “Password required for data on WebDAV” typically refers to your Enpass master password, which is needed to unlock the data stored on your WebDAV server.

If you’re certain the master password hasn’t changed but it’s still not being accepted, we recommend the following steps:

1. Go to Vault Settings > Sync for the affected vault.

2. Tap "Disconnect" to remove the current sync.

3. Then select "Set up Sync" again and reconfigure it with your WebDAV credentials.

Let us know if the issue persists or if you’d like assistance with any of the steps.

I “overwrote” the vault's master password and solved the problem. Can you tell me why the password is no longer accepted even though it hasn't been changed? I'm a little concerned because synchronization suddenly became impossible. Incidents like this cause you to lose confidence in the password manager.

[Amandeep Kumar]

We understand your concern. In rare cases, such issues can occur due to temporary inconsistencies in sync data, especially if there has been a network disruption, partial sync failure, or data corruption during communication with the WebDAV server. As a result, the app may no longer correctly recognize or decrypt the vault using the existing master password.

That said, incidents like these are taken seriously. We’ve already shared this behavior with our technical team for deeper investigation to ensure improved stability and reliability in future releases.

To help us further investigate the issue, could you please share the following details:

• The size of the Enpass .enpassdbsync file currently stored on your WebDAV server

• The WebDAV server version (if self-hosted), or the name of the service provider if you're using a third-party WebDAV service

• How frequently do you encounter this issue was it a one-time occurrence, or does it happen regularly?

We appreciate your cooperation and look forward to your response.

The size of Enpass vault.enpassdbsync of of the affected vault is 4 MB. This size also seems a bit large to me. I have another vault whose .enpassdbsync is 5.6 MB in size and contains very few entries.

The WebDAV Software ist MagentaCLOUD (German Telekom) which use Nextcloud Software. Unfortunately, I do not know the exact software version.

It only happened to me once. What was very strange was that it happened while I was on vacation and I accessed the vault from abroad. Between the last time I accessed it before leaving and the time I accessed it abroad, no one else accessed the vault.

I am always available to assist with troubleshooting. I have spent my entire professional career in software development.

Thank you for sharing the requested information and additional context. I’ll pass this along to our technical team for further investigation. If we require any further details, we’ll be sure to reach out to you.

We truly appreciate your patience and your willingness to assist with troubleshooting as we work to resolve this issue.

If the Enpass file size on the cloud appears to be 5.6 GB, this could be due to attachments stored within the vault. Could you please confirm whether the total file size is 5.6 GB, or if this size refers specifically to the .dbsync file?

Please let us know once you’ve checked the file details.
