As of a couple minutes ago you should no longer need to login each time to use the Premium Downloader.
Because the domain through which the Premium Downloader is integrated into Mobilism has changed to dl.mobilism.org (previously it was mblservices.org), you may need to save your Premium password in your browser again. To see what your previous saved password was, do the following:
For Chrome:1. Click on the three dots in the upper right-hand corner
2. Select Settings
3. In the search bar at the top that says "Search settings" type in password and press enter. There will be a result titled "Passwords" with a key icon. Click on it.
4. In the upper right-hand corner will be a field called "Search passwords" - type mblservices.org and press enter in it.
5. Your saved login will be listed below. Click on the eye icon to the right of it and enter your login if prompted for your saved password to be shown.
For Firefox:1. Click on the three lines in the upper right-hand corner
2. Select Settings
3. In the search bar at the top that says "Find in settings" type in password and press enter. There will be a result in bold titled "Logins and Passwords" and next to it a button titled "Saved Logins..." - click on that button.
4. Type in mblservices.org, select the account from the results on the left side, and press the eye icon next to the password to reveal it
For Chrome mobile:1. Click on the three dots in the upper right-hand corner
2. Click on Settings > Passwords
3. Click on the magnifying glass/search icon at the top

Alternatively you can reset your Premium password by clicking Forgot Password
