Forgetting your iPhone X password can be a frustrating experience, but fortunately, there are a few methods you can try to unlock it without the password. Here are some steps you can take:

1. Use Face ID: If you have set up Face ID on your iPhone X, you can simply look at your phone to unlock it.
2. Use Siri: You can try using Siri to unlock your phone by saying 'Hey Siri, unlock my iPhone'.
3. Use Find My iPhone: If you have enabled Find My iPhone feature, you can erase your device and set it up as a new one.
4. Restore via iTunes: Connect your iPhone X to a computer with iTunes and perform a restore to unlock it.

Remember, it's important to keep your passwords secure and easily accessible in case of such situations.
