Today I decided to change the password of my iCloud account. I did so from the browser of my Mac. Then I thought I had to update it also on all my devices but surprisingly I did not have to. Is this normal?
This is normal behavior and helps illustrate how things work technically behind the scenes a bit.
When you enter your AppleID or password, Apple generally never stores that and instead makes a secure token derived from elements including your password that then is stored and identifies that specific device to the servers that provide sync or services.
When you change your password, that prompts (optionally) to renew that cookie or certificate but doesn’t stop syncing of data just because a routine password change has arrived.
This lets Apple minimize risk and disruption when you ask to update your password versus having a more urgent need to tie all the devices together and break / deny service when a lock out or forced change is happening.
As I understand you change the Password of your AppleID - do you think so?
Apple never Share passwords to other devices and never have access to this. Your AppleID password is synonymous with your iCloud. If you change your AppleID Password this will encrypt your iCloud with your new Password.
To access in your iCloud with your devices:
- Log out from iCloud of all your devices
- Log in with your new Password.
For the next Time if you need to change your password this is the right way:
