If you’re putting all of your OTP codes in your password manager, that completely negates the entire point of two factor authentication.
And sure, maybe you think “well I’m not a high value target anyway, I don’t need to really secure my devices”, how many of you have work-related accounts signed into your devices? Even if you’re just a lowly engineer, I can guarantee you absolutely are a target of sophisticated hacker groups (ironically you may even be more of a target because these groups know that you don’t consider yourself a target and therefor are more lax with your security).
