Assistance on understanding feasibilities to avoid repeated manual login

[AmeyGa]

The requirement is to avoid repeated manual login.
Thus, need assistance on the following pointers as what is supported/feasible:
1. Is there a way to generate permanent access and refresh tokens that do not expire?
2. If not, is there any permanent code/secret/token that can be used to avoid login process to SaaS during the 2 step OAuth2 authentication process?
3. If none of the above are feasible, is the user allowed to use scripts to perform login?

I'm assuming this is for Analytics/CJA rather than anything else eg. API calls, Report Builder, etc.

In the Admin section (https://adminconsole.adobe.com/), there is a setting for the Max session life/Max idle time:

Settings > Privacy & security > Authentication settings

If you find users are being asked to log in to AEP/CJA/etc. an annoying amount of times, you can alter these. Both settings won't apply to all products, but altering them should allow users more time per session. 
You could also remove the need for 2FA (if you have that on), but I don't think there's a reason to do that.
