A File Browser login failure after a ZimaOS update initially looked like an application regression. The successful community fix was simpler: after a clean initialization, File Browser generated a new password for the admin account and printed it in the application logs.
Why Old Credentials Stop Working After a Clean Reset
Current File Browser behavior supports what the thread showed. The official File Browser first boot says a fresh instance bootstraps its database and prints a randomly generated admin password in the console logs. That password is shown only once during initialization.
The File Browser authentication also documents File Browser's own authentication layer. ZimaOS user credentials and File Browser application credentials are therefore not automatically interchangeable.
Find the Password in ZimaOS App Logs
Open the File Browser application settings in ZimaOS, then open the log view and look for the first initialization messages. In the original screenshot, the important line is the one that says the admin user was initialized with a randomly generated password.
Why Deleting Only Some Files Can Be Confusing
File Browser persists its database and configuration separately. A partial reset can leave you with a different combination of database, settings, and expected credentials. The first Docker app explains why persistent container data survives ordinary app restarts, while the ZimaOS App Store requirements provides the broader current ZimaOS app context.
If the app is being used as part of a larger storage workflow, the ZimaOS cloud integration is also useful for deciding which files belong in application storage versus the main ZimaOS data volumes.
If the Generated Password Is No Longer Visible
Do not guess passwords repeatedly. First determine whether the database was recreated and whether the original initialization logs still exist. Upstream File Browser warns that the generated password is displayed only once; if it is lost, use the current upstream reset/reinitialization method rather than copying credentials from another installation.
Bottom Line
In this community case, File Browser itself was working. The login changed because a clean initialization generated a new admin password. Check the application logs immediately after initialization and keep ZimaOS account credentials separate from File Browser's own authentication database.
