I looked in https://docs.cloudron.io/apps/bitwardenrs/ without success: How do I delete a user that has signed up to my bitwarden instance? I had registration open by mistake and someone actually signed up
@necrevistonnezr I am not using bitwarden on Cloudron, but in general you can enable an admin interface, which would then be available at https://your-bitwarden.cloudron/admin.
From that interface you can delete users.
@fbartels Thanks for the hint!
I have added a doc section now - https://docs.cloudron.io/apps/bitwardenrs/#admin
Thanks to both of you!
