I need your database layout reccmendations (for the best efficienty etc..)

I am keeping this as short as I can. I am building a site where the user saves “notes”

Notes are purely text and the user should be able to make multiple notes under different name.

I have no idea how I am going to arrange this into a table 0_0

Like should my table columns be like this

Username | Password | IDno. | Notes |

And stuff all of the user’s notes into a single column…? I am confus >.<
Or should I just separate the IDno. column and Notes into

btw I really need IDno. column as the site isn’t going to represent users by their username, just their ID no.

Thanks in advance.

Users
- user_id: pk
- email
- pass

Notes
- note_id: pk
- user_id: fk (what user posted the note)
- title
- message
