How do I change the email password on IOS 16?

Hello dtomaselli5541,

Thanks for using the Apple Support Communities!

Are you trying to change the password for the account or simply updated it on your iPhone after having already changed it?

If you're wanting to change the account password you'll want to reach out to your email provider for steps for that. If your provider is iCloud, this can help: Change your Apple ID password

Hope this helps!
