Iforgot

Hello Lunty1980,

Welcome to Apple Support Communities. 

We understand that your daughter’s iPhone won’t power on and she has a new iPhone but forgot her Apple ID password. we are happy to help.

While your daughter can proceed to set up her iPhone without an Apple ID or a new Apple ID for now, she wouldn’t have her purchased content or content synced to iCloud such as photos, contacts, mail, etc. Based upon what you have mentioned, it sounds like your daughter may be in account recovery. Here’s more information on account recovery: How to use account recovery when you can’t reset your Apple ID password - Apple Support

"After you start account recovery

After you request account recovery, you get an email with a confirmation of your request and the date and time of when you can expect to regain access. This email arrives within 72 hours.

• If you submitted your account recovery request with iforgot.apple.com through your device's browser, you should avoid using that device during this period. Using that device might cancel account recovery. 
• To avoid delays, turn off other devices that are signed in with your Apple ID until account recovery is complete. 

When the wait period is over, Apple sends you a text or automated phone call with instructions to regain access to your account. Follow the instructions to immediately regain access to your Apple ID.

In some cases, you might be able to speed up the account recovery process or reset your password immediately by verifying a six-digit code sent to your primary email address. You might also be able to shorten the wait time by providing credit-card details to confirm your identity. If you’re given this option, an authorization request goes to the card issuer.*

Check the status of your request

At any time, you can see how long it will be until your account is ready for recovery, or when more information will be available. Just go to iforgot.apple.com and enter your Apple ID."

Take care.
