Change the authentication method to use only password in Ezeelogin
How do I change the authentication method to use only password to remote servers added in Ezeelogin?
The following steps will clear the global key saved on the remote server and all private keys stored in Ezeelogin.
After completing all these steps and attempting to log in to the remote server, the authentication method used will be password-based.
Replace the private key ID with zero to unassign the saved private key for a server or server group.
It is recommended to use key-based authentication for remote servers accessed through Ezeelogin.
The priority of authentication methods used in Ezeelogin is as follows:
1. Key saved while adding the server (SSH Private Key).
2. Saved private key stored in key management.
3. Global key (Ezeelogin key).
4. Password-based authentication, which is the least preferred method.
