As long as you remember your current My Eyes Only passcode, you can change your passcode at any time.
To change your My Eyes Only passcode…
- Swipe left in Memories until you reach ‘My Eyes Only’
- Tap ‘Options’
- Tap ‘Change Passcode'
- Enter your current passcode
- Create a new passcode and enter it a second time to confirm it
- Acknowledge that if you forget your passcode, Snapchat won’t be able to recover it or your private Snaps and tap ‘Continue’
- Tap ‘Finish’
If you don’t want to use a 4-digit passcode, you can create an alphanumeric passphrase instead. Just tap ‘Use Passphrase 🔐’ at the bottom of the ‘Create New Passcode’ screen.
