Password issue with CUPS.

**TL;DR:** Need workaround for CUPS printer password to print from mobile (Android).

Please note that **I am a beginner** to using CUPS, so my knowledge is very limited to my experimentation. I have set up my router as a print server. Issue is that to print anything, I need to enter the router's username and password (the one used to log into router settings).

This is not an issue on my PC (POP!\_OS), but mobile phones do not ask for passwords when printing and it fails to even recognise that a printer exists. The only way I have been able to enter a password is through my PC's GUI, no terminal or CUPS webpage. Till now I have thought of 3 solutions (in no particular order):

1. **Use my PC to create a "rebroadcasted" printer.** This seems to happen automatically when sharing the print server's printer. The issue still is that even though it successfully forwards to job to the proper place, it doesn't fix the fact that it requires password. The printer page on CUPS just shows "authentication required", with no intuitive way to input password (even from the CUPS webpage itself) 2. **Somehow access the CUPS service on the router.** This could be the best option if it works, since I can entirely disable the password and enable network-wide sharing. 3. **Find a way to enter username and password on android.** This could also be a great option, since it might be just as good as option 2 considering my use-case.

Any help is appreciated!
