Access token expire every day

Do i need to generate access token every day? how the access token remains valid?. every day I get below error.

iteconnect.exceptions.TokenException: Incorrect `api_key` or `access_token`.

to solve every day I do following
1. get kite URL (kite.login_url())
2. https://kite.trade/connect/login?api_key=??????????=3
3. get request token
4. generate session (kite.generate_session("QiMAh3CndfgdfgdfgfdY6fBjS1doC2NT", api_secret=api_secret))
5. and then set access token (kite.set_access_token("z0gxN7qsYsdffdgdfgdfYlXEOzrl7T"))


This is time consuming process every day and defeats the purpose of working API.

Any solutions?

Note : all the parameter used above is scrambled
