Company sends email notifying us we'd need to register for two factor authentication because it would be mandatory for all access to email within a week. However, it had to get manager approval and had a side effect of giving us access to work from home (which my manager hates). So, we send the request to him, explain the situation, he denies it and says "that can't be right! Let's do this: if you do in fact lose access to email, then I'll approve it". Well, we did lose it, and just spent two days without any access to email and it was a huge pain to get the registration process done because one of its steps involved getting a validation code from the email.
