apg (Automated Password Generator) creates random passwords using either a pronounceable password algorithm (based on phoneme sequences) or completely random characters.
Pronounceable passwords are easier to remember but potentially less secure. Random passwords offer maximum entropy but are harder to memorize.

-a algorithm

Algorithm: 0=pronounceable, 1=random

Minimum password length

Maximum password length

Number of passwords to generate

Character classes: S=special, N=numeric, C=capital, L=lowercase

Exclude specific characters

Check against dictionary file

Quiet mode (passwords only)

Prompt for random seed

Spell pronounceable passwords

Pronounceable passwords may have patterns that reduce entropy. For high-security applications, use random mode with sufficient length. Output goes to terminal; pipe to clip for clipboard.

apg was created by Adel I. Mirzazhanov, implementing both random and pronounceable password generation algorithms for Unix systems.
