Hi saeyren. First, you posted this to a public forum which means it will be public and can be found thru a Google search.
As for your mother password issue. It sounds like she is starting account recovery which has s as few key points to keep in mind.
It’s a two phase process once started. Phase 1 is the evaluation period, usually 24-72 hours but can be longer or shorter. This phase says Apple is evaluating your info and you’ll get an update after the posted time is over (people mistakenly think it means they’ll be able to reset the password immediately after this first phase.)
Once phase 1 is done it enters phase 2 where https://iforgot.apple.com/ will give you the final amount of days (can be weeks) you’ll wait. On that final day you’ll get a text/email, follow that text/email immediately.
Second, which will likely explain why she’s not getting the notification to reset the password. Per How to use account recovery when you can’t reset your Apple ID password - Apple Support
- 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.
This basically means she should not do anything with the Apple ID like update or download apps, check iCloud email, listen to Music, Podcast, Books, News, try to sign in, etc. because it will cancel account recovery thinking she has access again and doesn’t need it reset anymore.
