Hello,

To recover snapchat account:

1. On your Camera screen, tap the profile icon at the top.
2. Tap the (settings) button to go to your settings.
3. Tap “Two-Factor Authentication”
4. Tap “Forget Devices”
5. Tap the button next to each device that you'd like to forget and tap “Yes” when prompted to confirm.

OR

Open up the Snapchat app, and then tap the “Log In” button. Next, type your username or email address, and then tap the “Forgot Your Password ” link. You'll have the choice of receiving a verification code via an SMS text message to your phone or using your email address to reset it.

All the best!

Hope it will help!

Thank you!
