Hello! My name is*****I am a certified computer professional who will assist you.
Please tell me how exactly you changed the Apple ID password ***** describe the process.
Yes, that is the proper reset password ***** What error message do you see on Whatsapp?
Please test the password ***** signing out of the Apple account on your iPhone and signing back in by doing the following:
1. On the home screen, tap on Settings2. Tap on iTunes & App Store3. Tap on your current Apple ID shown at the top4. Tap on Sign Out in the popup menu that appears5. You can now sign back in using the same account, just make sure to use the latest password
Let me know if you could sign back in.
It seems something is wrong with your iPhone. It looks like it is refusing any Apple ID you enter.
The Secure Remote assistance works only with computers and is not supported for phones, unfortunately.
For that reason, let's continue using this chat mode. I have several suggestions for you to try.
First, completely shut down your iPhone and leave it powered off for 2 minutes. After that, power it back on and then go to Settings and tap on iTunes & App Store again, as I mentioned. Test both Apple IDs.
In case it still refuses to accept them, you can change the network connection and try to sign in again. For example, if you are now connected to your home WiFi network, you can disconnect from it and then switch to another WiFi network if available, or disable the WiFi completely and enable the mobile broadband and then check if you can sign into one of your Apple IDs.
Let me know the results.
OK. Are you able to fully sign out of the current Apple ID by going to Settings > iTunes & App Store > Sign Out?
Interesting. Sure, try it and let me know what happened.
That's because you haven't fully signed out of the previous Apple ID. Please go to Settings > iTunes & App Store and sign out from the current account. After that, go to Settings > iCloud and sign out there as well.
After that, sign in there using the other Apple ID that seems to be working now.
In that case, I would recommend you to uninstall Whatsapp and re-install it, but since you don't want to lose the contacts and messages, let me check if the contacts and messages can be synced back once you re-install Whatsapp. Hold on...
It looks like WhatsApp re-installation won't affect the contacts since it uses the phone's contacts, but will affect the saved messages since they are saved in a phone, rather than in a cloud. For that reason, do no uninstall WhatsApp just yet, but check out these WhatsApp messages backup methods.
If you can use one of the described methods to backup the messages, you can safely uninstall and then re-install WhatsApp on your iPhone.
Hello again!I am following up with you to see if you require further assistance. Let me know by sending me a reply below.Thanks,IT Miro
Hello! That's fine. Let me know what you decided to do with WhatsApp. Were you able to backup its messages and re-install it?
Thanks - reviewing them now...
Since it looks like there is no way to run the backup of messages through WhatsApp settings, and I see your iPhone still won't accept the password ***** the original Apple ID used to install WhatsApp, you can create a backup of your entire phone using iTunes or iCloud, and then extract the WhatsApp messages using a program called iPhone Backup Extractor.
The instructions are described here:
Once you have the WhatsApp messages saved on your computer, you can go ahead and uninstall WhatsApp on your iPhone and then re-install it using the Apple ID that your phone accepts.
Hopefully, the backup method I suggested will work for you. It is possible that the messages will remain on the phone even though you uninstall and reinstall WhatsApp.
When re-installing WhatsApp, use the Apple ID that your iPhone can access.
