I want to change my account password via the web browser.

I just created my platformio membership. I became a member by connecting to github. For this reason, I did not set any password. However, I need to enter a password to log in to my membership through the program. I could not find how to change the password via the web browser. Can you help with this ?

Same Problem here, my main workstation logs me in automatic, but from other computers I need password etc, I can not login, password too short

Kind Regards
