@Vasilii please check if dashboard module is enabled with the command:

ceph mgr module ls

If the module is not enable then the "set-login-credentials" is also not available.

Are we talking about dashboard in Luminous (12.x) or Mimic (13.x)? The link to the documentation your referering is for Mimic, so

ceph dashboard set-login-credentials
