Click on the pencil, top left.
then tick the one that you want to delete, and press Delete at the bottom.
That is for IOS apps only! Does not work for androids as the method is different.
Thank you for the reply, but I don't have anything to click on top left side.
There is a blue color bar titled Google Authenticator and three dots on the top right hand corner, which expands to "How it works", View in dark mode", "Settings" and "Help & feedback" none of which does not give me an option to remove entries.
I am using an android smartphone.
Ah yeah figured that much because I had the same issues when going from IOS to Android OS. What you do is you hold down the one you want to delete for 3-5 seconds. It should turn a different
shade then the rest of them and have three little lines to the left side of it (those are irrelevant but they should be there)...look to the top right hand corner of your screen and there will be a trash
can button there. To reiterate the process is hold down 3-5 secs then top right corner there will be a trash can to delete the one selected. That should work, I have used it multiple times. GL!
