If mutual trust is configured, it doesn’t have much impact.
It should not affect the cluster, as long as you configure passwordless mutual trust according to the standard deployment.
Using tiup for installation, the TiDB user SSH key is used to run it, and it does not affect changing the server password.
Did you configure SSH mutual trust?
SSH key authentication does not require a username and password.
If the SSH version has been upgraded, it seems that upgrading the SSH version might affect the SSH key.
Reconfigure SSH mutual trust after the upgrade.
Upgrading carries risks [sneaky smile], make sure to back up properly.
