Authorization or authentication

Thank you so much
Appreciate

i read article in theory, what is Authorization. Authorization used new world to authorize third-party access. like to access to google sheet.

Here cake use similar by allowing resources. but in IT fundamental is terminology correct?

We have two types of access SAML and Authorisation.

I directly can see authentication as SAML.

is there any security risks of using authorisation due to mis-interpretation?
