You're probably seeing this because you've used a normal (not incognito) browser to log into ukpunting.
To stop the autofill of the domain name, in a normal browser:
- Go into browser menu, the three vertical dots at the top right.
- Select History and go to the "History" selection above the list of recent history.
- Use the Search (top right) to search for ukpunting and delete the lines.
- If it still autofills, there's probably a bookmark to the site, just delete it.
To stop the name autofilling, again in a normal browser:
- start typing your user name until it shows as an option you can select.
- Down arrow to select the username and press Shift and Delete, the name should disappear.
To stop your password being remembered go to the menu in a normal browser:
- Select settings.
- Search for password, you'll see "password manager", select that.
- Find ukpunting in the list of sites, click the 3 dots to the right (more actions) and select Remove
There's also an option to save usernames / passwords in a google account that works across multiple devices. I don't use that so not sure how to fix it.
Hope that helps.
