I am no longer able to sign in on desktop

Hi @Reuben28779839i8fx,

Hope you are doing well. Sorry for your experience with Acrobat Sign-in.

Have you tried clearing the cache file, resetting the browser data, and then checking? 

You might try the steps as per the web browsers you use:

1. Microsoft Edge: Reset Microsoft Edge data in the cloud | Microsoft Learn

2. Firefox: How to clear the Firefox cache | Firefox Help (mozilla.org)

3. Google Chrome: Clear cache & cookies - Computer - Google Account Help

4. Apple Safari: Clear cookies in Safari on Mac - Apple Support (IN)

Once done, you might want to try logging in again.

Hope this helps.
