ssk-key password: necessary to update?

[Sthu Deus <sthu.deus@gmail.com>]

Good day.


If I want to change ssh-key for a remote machine, for security reason - do I have to change its password too (that protects the key use) - or I can live it the same - as it remains on local machine and therefore, not known/transmitted to the remote one?


Thanks for Your time.
