improved persistent login cookie best practice

you use strategy described here best practice (2006) or an updated strategy described here (2015):

1. when user logs in remember me checked, login cookie issued in addition standard session management cookie.
2. the login cookie contains a series identifier , token. series , token unguessable random numbers suitably large space. both stored in database table, the token hashed (sha256 fine).
3. when non-logged-in user visits site , presents login cookie, series identifier looked in database.
   1. if series identifier present , hash of token matches hash series identifier, user considered authenticated. new token generated, new hash token stored on old record, , new login cookie issued user (it's okay re-use series identifier).
   2. if series present token not match, theft assumed. user receives worded warning , of user's remembered sessions deleted.
   3. if username , series not present, login cookie ignored.

this approach provides defense-in-depth. if manages leak database table, not give attacker open door impersonating users.
