Admin plugin isn't work

I am new in this, so I'm following the tutorial and I have stopped in the administration panel installation because I had the manual installation following all steps. When I have tried to access through mylocalhost/Grav/admin, everytime it says me "Login failed". I don't understand because I have configured admin.yaml in user/accounts with my data. Someone knows how can help me? Thank you soo much!

Can you paste your admin.yaml file, to see if there's any obvious error?

Of course,

password: '***'
email: '[email protected]'
fullname: 'Cristina'
title: 'Site Administrator'
access:
admin:
login: true
super: true

Could just be a problem of indentation/quotes, try with

password: test
email: t[email protected]
fullname: Test
title: Test
access:
    admin:
        login: true
        super: true
---

This isn't work neither.

Put your user/ folder zipped on dropbox or similar and paste me the link via PM on Gitter, I'll take a look

[SOLVED] I wrote like Username my email and my fullname but it wasn't correct. You have to write like Username > 'admin' and your own password.
