11 .SH DESCRIPTION | |
12 .I Passwd | |
13 changes the invoker's Plan 9 password and/or APOP secret. | |
14 The Plan 9 password is used to login to a terminal while | |
15 the APOP secret is used for a number of external services: | |
16 POP3, IMAP, and VPN access. The optional argument specifies | |
17 the user name and authentication domain to use if different | |
18 than the one associated with the machine | |
19 .I passwd | |
20 is run on. | |
21 .PP | |
22 The program first prompts for the old Plan 9 password in the specified | |
23 domain to establish | |
24 identity. | |
25 It then prompts for changes to the password and the | |
26 secret. | |
27 New passwords and secrets must be typed twice, to forestall mistakes. | |
28 New passwords must be sufficiently hard to guess. | |
29 They may be of any length greater than seven characters. | |
30 .PP | |
31 .I Netkey | |
32 prompts for a password to encrypt network challenges. | |
33 It is a substitute for a SecureNet box. | |
