The "userpass" credential provider allows you to authenticate with
a username and password. To use it, specify the "username" and "password"
parameters. If password is not provided on the command line, it will be
read from stdin.
If multi-factor authentication (MFA) is enabled, a "method" and/or "passcode"
may be provided depending on the MFA backend enabled. To check
which MFA backend is in use, read "auth/[mount]/mfa_config".
Example: vault auth -method=userpass \
username=<user> \
password=<password>
