Here is the fix.
1. Open up the Facebook that you use to log into tunesat.
2. Click settings and privacy, and then settings.
3. Click apps and websites
4. Find Tunesat then click View and edit
5. Take a note of the long reference number at the bottom where it says about contacting TuneSat.
6. Go back to tunesat login and hit forgot my password
7. Put in that code you copied down
It will then send a password reset to the email accociated with the Facebook account and you can reset it and login. I think this disconnects it from Facebook so you’ll then always have to log in with the number. But it works!
