Apple Watch SE not accepting correct password

To fix an Apple Watch SE that rejects your correct Apple ID password, sign out and back into your Apple Account directly through the companion Watch app on your paired iPhone, or unpair and re-pair the watch.

Try this

• Type directly on the watch: If the password prompt relays from your iPhone keyboard, special characters or typos can cause validation loops. Try typing your password directly on the Apple Watch keyboard. 
• Restart both devices: Turn off both your Apple Watch and your paired iPhone, then turn them back on to clear temporary communication glitches. 
• Check for secondary Apple IDs: The watch may be asking for an older Apple ID previously used for media, app purchases, or family sharing rather than your primary iCloud account. 

This has worked reset the watch and installed from backup <3

Welcome and thank you for reaching out. 🤗

How to reset your Apple Watch if you forgot your passcode:



1. Put your watch on its charger and keep it there until you complete these steps.
2. Press and hold the side button until you see Power Off.
3. Press and hold the Digital Crown until you see Erase all content and settings.
4. Tap Reset, then tap Reset again to confirm.
5. Wait for the process to finish, then set up your Apple Watch again. When asked, restore from a backup.

NOTE — Erasing all content and settings erases all media, data, and settings from your Apple Watch, but it does not remove Activation Lock. To remove Activation Lock, unpair the watch first. Before your watch is erased, a backup of its contents is created on your iPhone.

Unfortunately none of those seem to be the issue, the only thing left is to try to unpair and repair it. Thanks for the reply.
