• man 1 'htpasswd' [EN]

Syntax

htpasswd [PARAMETER ...] [FILE] USER [PASSWORD]

Parameters

-B

Use bcrypt encryption for passwords. This is currently considered to be very secure.

-c

Create the passwdfile. If passwdfile already exists, it is rewritten and truncated.

-C

This flag is only allowed in combination with -B (bcrypt encryption). It sets the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 31).

-D

Delete user. If the username exists in the specified htpasswd file, it will be deleted.

-i

Read the password from stdin without verification (for script usage).

-v

Verify password. Verify that the given password matches the password of the user stored in the specified htpasswd file. Available in 2.4.5 and later.

Examples

Create a new file and add the user "alex"

htpasswd -c -B '/var/www/htusers' 'alex'
