[code]

                           Configuring User Accounts 

   User accounts provide one way for users to access the router. (Users can
   access the router without accounts if you configured RADIUS or TACACS+
   servers, as described in Configuring User Authentication.) For each
   account, you define the login name for the user and, optionally,
   information that identifies the user. After you have created an account,
   the software creates a home directory for the user.
   To create user accounts, include the user statement at the [edit system
   login] hierarchy level:
     [edit system login]
     user username {
         full-name complete-name;
         uid uid-value;
         class class-name;
         authentication {
             (encrypted-password "password" | plain-text-password);
             ssh-rsa "public-key";
             ssh-dsa "public-key";
         }
     }
   For each user account, you can define the following:
     * Username--(Optional) Name that identifies the user. It must be unique
---(more)---
[/code]

Help reference(参考)

root@Junos> help reference system user-login
user (Access)

  Syntax

     user username {
         full-name complete-name;
         uid uid-value;

         authentication {
             (encrypted-password "password" | plain-text-password);
             ssh-rsa "public-key";
             ssh-dsa "public-key";
         }
     }
