Reset forgotten password?

Hello, I've been using planka for a couple of months now and have a lot of data on it. I've run into an issue twice now where I was somehow locked outside and could not access it. Once was when I migrated to a new form of docker, luckily then I had a backup of the db folder, so I just pointed the docker to that, and I was good. Now is the second time, since it won't accept my password. What I suspect happened was during the first issue I mentioned, there was a time I tried setting up planka from scratch and forgot about the backup. That password was saved to my browser on top of the old one.

Anyway, now I am stuck outside the gui, with no password and no way back in, since if I remember correctly, I removed the demo account.

I tried accessing the password from the postgress db, but my knowledge of db syntax is limited, and I doubt it's saved there anyway in plain text.

How can I get back in then? If not, is there a way for me to get the data out? Also, there should be a way to export/backup boards or projects outside in case you want to migrate them to another instance. Thanks.
