Two openai.com accounts on same computer , can or no-can?

Hello ,
I have two computers:
A) is ‘a paid account’ ChatGpt4Plus.
B) is a free account .
On B I did a Windows Reset
and prepared B for the sole purpose of tinkering with ChatHub .
And set up a free openai.com account .
The problem I am having is that I can’t
login to my 'paid for account on B computer …

Is there a way around that ?
Thanks for your help!

I don’t know what your problem would be, except for the configuration of the second computer.

I can log into a second ChatGPT account simply by launching a “private browser window”.
