etrade supports hardware 2fa. oh, not like that, no - it's a keychain thing that displays a numeric code, like the RSA tokens from the 2000s. you have to buy one and they ship it to you. totally phishable.
@surfingalot etrade also has mobile app 2fa, but it's some proprietary symantec garbage and not standard TOTP and i'm not installing any proprietary 2FA app on my phone.
