DESCRIPTION
pwtool is a utility to add generate account passwords in a variety of formats with helper output on stdout. By default the password strings are made of of letters and numbers for easy mouse selection.

As well as flexible password generation options a main goal is to output user creation strings to copy and paste/execute as stdin so that operators don’t have to re-type passwords.

Crypts can be based on user supplied strings via the --password option or PASSWORD environment variable.

The --format string can expand values:

        pwtool --database billing --username wonkeydonkey --password hunter2 --servername webby --number 1 --format 'DB: %{database}\\nUSR: %{username}\\nPASSWORD: %{password}\\nSERVER: %{servername}\\n'

Other strings, such as --mysqlfmt, --pgfmt, --mysqluserfmt, --userfmt, can generate copy/paste shell commands:

        pwtool --username wonkeydonkey --number 1 --userfmt

        useradd -m -s /bin/bash -p '$5$hYhnxam4j/chBu3V$BsZsRl4nj6DTpEdFMfLuerPFR0xvCJmeGQCUjuG9qM1' wonkeydonkey # Y9YgmSyv1A

        pwtool --username wonkeydonkey --database circus --createdatabase --number 1 --mysqlfmt

        create database circus; grant all privileges on circus.* to wonkeydonkey@'%' identified with mysql_native_password as '*21c0a42c1bb43ff6b56226a6a65a8859dd077497'; -- # VfKptnR2ft

TOTP
pwtool can work as a TOTP CLI and display TOTP authentication strings.

If you want to leave a TOTP authentication display in your terminal, it can run like this:

        TOTP=metalisbest pwtool --totpfmt --loopdelay 1

It will then run and leave a display like this:

        202924 [#########################     ]

If you have multiple accounts, they can be displayed like this:

TOTP=“metalisbest;grungeisbest” pwtool –totpfmt –loopdelay 1

        617989 [##################            ]
        826783 [##################            ]

That doesn’t show you the names, so you can include that with key=value strings:

        TOTP="key=metalisbest,name=metal;key=grungeisbest,name=grunge" pwtool --format "%{totpfmt} %{username}\n" --loopdelay 1

        488833 [#################             ] metal
        967495 [#################             ] grunge

The following key=value pairs are supported:

key | definition
key / totp | the totp string
name / username | a meaningful name for this key
step | number of step seconds
digits | the length of the output
algo | which hmac to use (sha1, sha256, sha512)
seconds | a user-defined time
