Storing login information in Cookies

Question

I want to save user\'s authentication information in browser cookie for persistent login. As they say, its never safe to store any secret info (such as password) in cookie, but

Answer 1

There is another option.

For each user, upon logging in and requesting to be remembered, create a long random string.

Store this string, along with the userId, in the cookie you give to the user.
Store a properly salted hash of the string in your db.

If the user presents a remember-me cookie, match the random string to the hashed verifier you have in your database (just as if it where a password).

If it matches -> log the user in and create a new remember-me cookie for them.
If doen't match -> request username and password.
