Do not allow the creation of additional accounts in Vaultwarden

In the environment variables, I set

SIGNUPS_ALLOWED=false

but it still allows accounts to be created.

If anyone has the answer, I would appreciate the help.

Maybe something to check with Vaultwarden developer

I use also vaultwarden but I can no replicate this. I have also set SIGNUPS_ALLOWED=false and I have the button to create an account, but I get always the message “Registration not allowed or user already exists” and of course I tried to add a non-existing user.
Did you restart the service after changing the config?

And can you check for duplicates in your config:

grep SIGNUPS_ALLOWED /mnt/dietpi_userdata/vaultwarden/vaultwarden.env

This settings gets also overridden if you have set SIGNUPS_DOMAINS_WHITELIST
