At some point it was supposed to ask me to configure an account with my email and password, but it never did, now I am able to get to the home screen but I cannot login because I did not configure an email and password. Any help is welcome, thank you!

Answer 1

I removed

/var/lib/pgadmin/pgadmin4.db 

file. It was first start pgadmin4 for me so there were nothing important

And then I run

sudo /usr/pgadmin4/bin/setup-web.sh

again and it ask for email\password
