@al- 

Try to do this action in an In-Private Edge session (right click your Edge icon and choose "New InPrivate Window")

navigate to the PowerApps.com site and login again there with your credentials.

I assume this works on other computers, so, does it work with your credentials on other computers as well?

If the InPrivate session works, then there is something gone wrong with your credentials in your browser.  I would consider a full logout in the browser.  Clear cache.  Restart browsers, etc.

I hope that is helpful for you.

@RandyHayes 

It still doesnt work 😞

I tried accessing my account through other people's laptop -- it worked. but for some reason, when i open power apps through my laptop, it displays the same error message.

@al- 

It sounds like the issue then is definitely on your computer.

You might want to go into the Windows Credential Manager and remove entries for your account that would be related to your login.  That would at least be my next step to take.

hi @RandyHayes 

thank you for your reply -- what do you mean remove the related logins? according to my web credentials, the only login I did with microsoft is the account i am currently using. would it be okay for you to expound what you mean?

many tanks,

@al- 

Yes, I would first determine how you are connected to your account - is it via login only, or do you have your work/school account connected to your Windows profile.  Also, even before that, is your computer joined to the Azure AD or is it on its own domain/workgroup?  If these don't apply and you are logging in through your browser sessions only, then I would next look to remove the reference to your login in the Credential Manager in Windows on that computer.  Go to the start menu and type Credential Manager.  In there you will see all of the places that Windows is recording and holding credential information.  I would remove the one for your Microsoft login, then attempt to log back in through the browser and see if the problem is resolved.

hey @RandyHayes 

thank you for taking the time to reply. i don't know what happened, but PowerApps is now working in my laptop.
