You could consider it if you were setting up a script to easily access a lot of accounts (think 10+) or have a machine without web browser to do the authorization.
I cannot see any need in your scenario. I prefer keeping things simple and using the most walked trails.
The thing to really protect is the tokens in your config file, they give access to your Drives without needing login credentials or 2FA.
The most important question is if other have access to read your account or files, or you are afraid of malware stealing your config file. If so then you should definitively protect it.
I encrypt my config and use the --config-command and the Windows Credential Manager to protect my password. This way you can only see/use the config if logged in as me, not sure how to best protect it on Linux.
Perhaps a Linux forum user can give a hint?
