# How to change the authorized amount when using DEX

We will use Metamask wallet as example.

#### 1. After connecting wallet, authorization will pop up, click Edit permission （The authorization will only appear on the first time when you using this DEX. If you have fully authorized previously and want to change the permission, please revoke the the original authorization first before proceeding. Please refer to the "How to View/Revoke Token Authorization" tutorial)
