16 mosquitto_passwd is a tool for managing password files for the
17 mosquitto MQTT broker.
18
19 Usernames must not contain ":". Passwords are stored in a similar
20 format to crypt(3).
21
23 -b
24 Run in batch mode. This allows the password to be provided at the
25 command line which can be convenient but should be used with care
26 because the password will be visible on the command line and in
27 command history.
28
29 -c
30 Create a new password file. If the file already exists, it will be
31 overwritten.
32
33 -D
34 Delete the specified user from the password file.
35
36 -U
37 This option can be used to upgrade/convert a password file with
38 plain text passwords into one using hashed passwords. It will
39 modify the specified file. It does not detect whether passwords are
40 already hashed, so using it on a password file that already
41 contains hashed passwords will generate new hashes based on the old
42 hashes and render the password file unusable.
43
44 passwordfile
45 The password file to modify.
46
47 username
48 The username to add/update/delete.
49
50 password
51 The password to use when in batch mode.
52
54 Add a user to a new password file:
55
56 · mosquitto_passwd -c /etc/mosquitto/passwd ral
57
58 Delete a user from a password file
59
60 · mosquitto_passwd -D /etc/mosquitto/passwd ral
