Hadn’t heard of this before. I’ll give it a whirl.

Is *warden the new hotness? Bitwarden, vaultwarden, linkwarden and now certwarden?

I have found, several years after deleting my Google accounts, that any accounts I missed, can be fixed with an email to support explaining I no longer have access to that gmail account. Sometimes I have to provide some understandable proof like an old purchase detail. The one or two accounts that didn’t have good support to help, were no real loss to create a new account for.
