I registered with cozy cloud and set it up - had no issues.
If there’s any difference: I did login by entering the mycozy subdomain instance for the newly created user.
That said - It’s not impossible for data state do cause a crash, I just had 1 test item in the password store.
Until it’s figured out - a fallback you can login into the website.
some bitwarden api poking
Interestingly, the client self-reports as bitwarden mobile based, I wonder if you can just point the regular bitwarden client to YOURSUBDOMAIN-passwords.mycozy.cloud or without -passwords - it’s API compatible but I’m missing something still to make it work. It will accept the /bitwarden/api path though, then credentials fail
I think I have solved my problem though. I had imported all my passwords from Proton Pass into Twake Pass but after deleting all the passwords again it works. Until now I have put in two passwords manually and it works on both my phone, browser extension and online.
