Specify User Login Credentials

User login credentials include a username and password.

Note:

Two types of password encryption are supported, SHA-1 and MD5. Secure Hash Algorithms

(SHA) are cryptographic has functions structured differently and are distinguished by the appended
number, such as -1. Message-Digest Algorithm is a cryptographic has function that produces a 128
bit (16 byte) hash value.

Control what it takes for the specified user to log in. The first three commands set a password on

the account.

The 0 flavor allows the password to be specified in cleartext.

The 7 flavor allows the password to be provided in the same encrypted form in which it would
be stored in the password file. This is useful for the

show configuration

command, since

the cleartext password cannot be recovered after it is set. These two commands are thus named
for Cisco compatibility.

The

nopassword

command means that no password is required to log in. The

disable

command

configures the account so that no one can log into that account.

The

disable password

command leaves the account as a whole the same, but forbids login with

a password. It is assumed that ssh key access will be used instead. To re-enable the account, the user

must un-disable it, and put a password on it.

The

no username disable

command prints a message to this effect; it only exists

to avoid stumping users with an apparently irreversible command.

Disabling a user account does not terminate any current sessions that user has open; it just prevents

new sessions from being established.

Display Current User Name

show users

Display the username of the currently logged-in user, and the capabilities that user has.
