'No such interface “org.freedesktop.DBus.Properties” on object at path /org/freedesktop/secrets/collection/login' in snapcraft login

hi, please help me!

In case this is still an issue or if anyone else has the same problem, you need to login using the new login flow explained here: https://snapcraft.io/docs/snapcraft-authentication

Essentially, you need to create the environment variable with the authentication token, or use gnome-keyring.
