Encrypt password text during API call in swagger(flasgger)

Question

I am using flasgger to generate swagger UI for API's in flask.

I have an API endpoint http://localhost:5000/api/token which gives back token, if correct username and password is given, everything is fine, only problem is password is sent in clear text, I want to encrypt password while posting through swagger and decrypt it in flask.

curl generated is

curl -X POST "http://localhost:5000/api/token" -H "accept: application/json" -H "Content-Type: application/json" -d "{"password": "mypassword", "username": "myuser"}"

How can I encrypt password value in swagger or flasgger. I tried below but didn't see any change.

Token:
    type: object
    properties:
        username:
            type: string
            description: 'enter your username'
            example:"myuser"
        password:
            type: string
            description: 'enter your password'
            example: 'mypassword'
            format: base64

Thanks in advance!
