I created this ULI bundle.
https://github.com/woutersf/mautic-uli-bundle
It allows you to get a unique login link or any user via the console.
This makes it easy to log you in if you lost your credentials but still have access to the console:
php bin/console mautic:uli 1
gives you a uniqie url to log in as user 1
I think this should be in core (like in Drupal)
