Cakephp 3.8 - Token authentication

Hello, im new in cakephp and im trying to implement the use of tokens to authentication in my app, but i have not been able to find something clear to implement, and in cake’s blog there is not anything related to the use of tokens, i hope somebody can help me with this.

Are you using the Auth component or the new plugin? The latter has this.

would be there any problem if i implement that in my app? because that is released to cake 2

It’s version 2 of the authentication plugin, which works with Cake 3+.
