That's a silly interpretation of my point. Sure, log into work resources - including your work email - with your work computer. Email token auth works fine for your work context.

If you're mixing work resources and personal email (or vice-versa), you have a problem. You should never hand off control of your intimate personal life to the security (or lack thereof) of your employer. And vice versa; your employer should not trust putting their intellectual property on questionably secured personal computing devices.
