Amazon’s introduced a new feature for customers that’s designed to make the checkout process easier.

The “PayPhrase” payment shortcut lets customers authorize purchases without entering a username and password.

The way it works: Users log into their Amazon account and cobble together a phrase — anything you want, but not something that includes copyrighted material or trademarked phrases. Oh, and don’t use anything that’s “unlawful, libelous, defamatory, obscene, pornographic, indecent, lewd, harassing, threatening, harmful, invasive of privacy or publicity rights, abusive, inflammatory, or otherwise objectionable …”

Well, that limits a lot of creative phrasing, right?

A PayPhrase has to be at least two words, at least four characters, and can’t exceed 100 characters. No special characters or numbers are allowed.

The advantage: Family members can share a pay phrase, allowing all members to use the same account without having to log in.

Which could also be pretty expensive, if you’ve got free-spending teens or a spend-thrift spouse.
