Remember me Cookie best practice?

Question

I read about many old questions about this argument, and I thought that the best practice is to set up a cookie with username,user_id and a random

Answer 1

My approach is the following:

1. Hash the user_id
2. Generate an unique key for the user - md5(current_timestamp)
3. Save the key to the DB
4. Encode everything so it looks like a BS - base64
5. Save it in the cookie

So far, It has been working great for me :)
