Can I directly change the password of the Linux account ‘tidb’ (used during cluster deployment, and subsequently the default configuration for cluster management is also the ‘tidb’ account) if mutual trust and password-free login have already been set up on each server in the cluster and the cluster is running normally? Will it affect the cluster’s operation?

You can modify it. Changing the password does not affect the cluster operation. You can refer to this link:
