Thanks again @t0t0 for your quick answer.
Well I’ve tried to keep going but now I have errors everywhere I’m gonna share my code and I hope do not bother you all with this challenge, btw I feel is becoming harder.
Thanks you all for your help

Apologize for adding so much text. My main errors right know are trying to access localhost:4000/users (list all users) or localhost:4000/users/1 (show an user) both cases without a session I got a ERR_TOO_MANY_REDIRECTS to me seems I’m having a kind of cycle issue.
The other error is trying to access localhost:4000/sessions/new (for logging in and using a new window incognito mode)
