livecd ~ # passwd gentoo

You can now choose the new password or passphrase.

A valid password should be a mix of upper and lower case letters, digits, and
other characters. You can use a password containing at least 7 characters
from all of these classes, or a password containing at least 8 characters
from just 3 of these 4 classes.
An upper case letter that begins the password and a digit that ends it do not
count towards the number of character classes used.

A passphrase should be of at least 3 words, 11 to 72 characters long, and
contain enough different characters.

Alternatively, if no one else can see your terminal now, you can pick this as
your password: "You+Yogurt_chile".

Enter new password:
