Strong support for the strategy of not putting your TOTP/MFA in your password manager, which has been argued on HN in the past.

Agreed, but I think using the same device to access your password manager and for dev is asking for trouble in the first place.

Password managers assumes a non-compromised device. I don't think there exist a password manager that is explicitly designed for a compromised/hostile device.

A password manager + built-in TOTP on a dedicated device is fine for most general usage. Important TOTPs can go to Yubikeys.

i would also offer, do not use the same device for everything, make sure any local connectivity has firewalled [dot]finances, and [dot]tech lab from each other and else. you should probably split your network to further isolate.

use intentional spelling mistakes in your password vault, edit the password by hand. you also need to have some way of authenticating login components to be sure your running your version of login, and not a trojan login.

I suppose the inverse would be starting with a device that offers TOTP/MFA, and then making your password-manager/vault somehow available on that same device. In either case, bringing them together makes it easier for an attacker to compromise both at the same time.

On reflection, I've never actually put my (personal) password vault on my phone, but that may be less of a conscious security stance than fulfilling a millennial stereotype, where certain tasks (like big purchases) are reserved for "a real computer."

Closest I've gotten is having my USB backup keychain in the same pocket, so I could get to it in an emergency, but it's inconveniently air-gapped.

Or using a hardware authenticator.
