Auth/authorisation

Authentification is the process by which a computer system ensures the identity of a user. For example if you want to connect with your account Google you enter password, login. Then you have additionnal authentification like simple or double authentification. You can receive a code by SMS, mail or you can connect with Google Authentificator application.

Authorisation is the check process that tell you which resources you can access. In web development that call tokens which consists on granting you the access at resources. For example with Google application you can view my work on Google docs but you can't update it

For the authentifciation we use hashing method which consists in encrypt data but they can't be decrypted.
