Authy is a platform for Two-step Verification. But if you’ve found love in meanwhile, you might consider to close your account. In that case: Don’t look further, because I’m about to explain how you can do that in the Settings of your account.
I’ll show you below with pictures how I managed to remove my profile on a desktop computer:
1 Go to https://dashboard.authy.com and log in to your account
2 Click on your name in the upper right corner
and select Account.
3 Scroll down to the bottom till you see Delete account
and click on the Delete button.
4 Last step – Confirm that you want to close the account
A notice will appear that the account was marked for deletion. Your account will be removed in the next 24 hours.
