Cannot `snapcraft login`

I’m inside a multipass VM. Here’s the first thing I tried:

$ snapcraft login
No keyring found to store or retrieve credentials from.
Recommended resolution: Ensure the keyring is working or SNAPCRAFT_STORE_CREDENTIALS is correctly exported into the environment
For more information, check out: https://documentation.ubuntu.com/snapcraft/stable/how-to/publishing/authenticate
Full execution log: '/home/ubuntu/.local/state/snapcraft/log/snapcraft-20260311-112958.019200.log'

Since the docs say

Note that snapcraft login sometimes fails to unlock GNOME keyring when accessing a Linux system with a desktop environment from a virtual console or SSH. GNOME keyring will not present a CLI password prompt to unlock the keyring, causing Snapcraft to hang and timeout.

I proceeded to export the credentials from my host system:

$ snapcraft export-login snapcraft-credentials.txt
Enter your Ubuntu One e-mail address and password.
If you do not have an Ubuntu One account, you can create one at https://snapcraft.io/account
...
Exported login credentials to 'snapcraft-credentials.txt'

These credentials must be used on Snapcraft 7.2 or greater.
$ multipass transfer snapcraft-credentials.txt data-platform-dev2:/home/ubuntu/

But now:

$ export SNAPCRAFT_STORE_CREDENTIALS=(cat ~/snapcraft-credentials.txt)
$ snapcraft login
Cannot login with 'SNAPCRAFT_STORE_CREDENTIALS' set.
Recommended resolution: Unset 'SNAPCRAFT_STORE_CREDENTIALS' and try again.
Full execution log: '/home/ubuntu/.local/state/snapcraft/log/snapcraft-20260311-114500.881764.log'

I’m quite confused on how to proceed. Logs and snapcraft version:

I understand now: SNAPCRAFT_STORE_CREDENTIALS is meant to be used instead of snapcraft login (thanks @carlcsaposs !)

This wasn’t obvious to me when reading the error message or the documentation though.
