How to Remove Old Email Accounts So I just bought a new phone last week and I'm in the process of downloading all my apps and setting it up. I was trying to log into the Slack app when this pop-up appeared with a list of all the emails that I've ever used.

Half of them were old email accounts that I haven't used in a while and they ranged from Gmail to Yahoo to Outlook and even my old college email address showed up. Where are these emails stored and how can I remove them from my device?

I've wrecked my brain and could not figure this out. Any help would be appreciated!
From your screenshots, it looks like old logins saved in Chrome. If you've used Chrome to remember your login details for websites, that's what they'll be. They're synced across desktop as well as mobile Chrome installs via your Google account. The UI for selecting which login to use has changed recently, so it's natural that you might be surprised by it.

You can delete old login details from the Chrome settings, on PC or mobile. On Android, the steps are:


In Chrome, click the three dots button in the top-right
Choose Settings from the menu
Choose Passwords
Either turn off Save passwords to disable the feature entirely, or:


Click a site in the list
Click the bin/trashcan icon in the top-right to delete that password
Repeat that for all the old login details you want removed
