I recently attended a trouble call where the customer was complaining that there were multiple auto-complete username entries in the various web forms using Microsoft Edge. She explained that she wanted to delete these obsolete entries. Previously, she had managed to delete ALL of the auto-complete entries but that was overkill.
If you need to delete a single entry, try left clicking the 3 dots on the top right hand corner of the Edge browser.
Next, select the “settings” option at the bottom of the list.
After this scroll down the list and click the “View advanced settings” button.
Lastly, click the “Manage passwords” button.
You will now see a list of your auto-complete entries. Left click the unwanted entry and then click the cross on the right hand side that appears to delete this entry.
