Continuing the discussion from Accessing Yourls after fresh install:
I struggled with the same issue issue as the poster above. I could not access the Yourls admin interface after a fresh install. I was constantly met with the error “Invalid username or password”, despite using the username and password I entered during setup.
Somehow, along the way, the password that I entered when installing this app was NOT the password that was used. I found a completely different password in the config.php file. A potential replacing bug in Yunohost (?), as the password I received was:
jfRkfie@ld__PASSWORD__9fdMSjeMFkee
So, to find your password, login to your server and check out what is entered in the following file: /etc/yunohost/apps/yourls/conf/config.php
For example:
ssh admin@192.168.1.22 -p 22
export TERM=xterm
sudo nano /etc/yunohost/apps/yourls/conf/config.php
=yes=
