Bitwarden is a free and open-source password management service that stores sensitive information such as website credentials in an encrypted vault. This is a Bitwarden server API implementation written in Rust compatible with upstream Bitwarden clients, perfect for self-hosted deployment where running the official resource-heavy service might not be ideal.
When installing the Bitwarden container, the installer will install under Appdata directory as the root user, however once it is installed you can change the owner/group of it to whatever is required
Run the below command (from a terminal) to change the permissions if required.
sudo chown -R owner:group ~/.config/appdata/bitwarden
Having the owner group change will allow you to edit the files if required without running into permission issues.
