People shit on it for lack of dkim verification (mail spoofing) but it’s ok for me. If you enable beta in the setting you can even log into the webui with a normal OTP for 2fa instead of the pin+yubikey tap weird one they had before

https://github.com/LuckyTurtleDev/docker-images/tree/main/dockerfiles/anki

start with env var sync_user1=username:password or something like that

change server url in anki desktop or ankidroid to what you started in docker

done
