Some banks do it properly. For example, my local credit union does Google Authenticator (actually TOTP, but they call it Google Authenticator). I use it with Authy on F-Droid.

Please do not use Authy, lacks essential features and it was bought by a bad actor.

You have to think of a Bank's threat model though.

Account compromise is one threat, but the use of valid accounts for money laundering is another. In my view the reason they "get it wrong" is because they don't want you to be able to automate transactions, as that makes money laundering easier...

Therefore, they don't want to use standard TOTP because that's easy to automate. Requiring SMS based 2FA is harder (but not impossible, use a modem or maybe a SMS service.) And requiring a special app is quite difficult to automate.

OP's problem sounds like failure to plan. If you are going to suspend your cell plan, you should probably check your authenticator works or have a backup option before you travel to another country. I don't know what the viable alternative is. Passkeys have just as many issues when phones are stolen, lost or broken. You cannot expect consumers to store recovery codes. I do agree support of TOTP authenticators would h…

hardware tokens are the way! Everyone has had a house key their whole lives, and understands how to keep a spare to prevent lock-outs.

UBS Switzerland has a decent system. When I first opened the account 15 years ago we had a number pad of codes on paper we entered as the authentication. Then later we got a credit card sized electronic device where we enter a passcode and it gives us a one-time code to enter to login. And now we have an Access app - we go to the website, enter our contract number, point our phone at a QR code on the webpage and auth…

Zurich Kantonalbank (ZKB) has a very similar system, probably because they're also a big bank in Switzerland

think its a Europe thing, we have the same solution in Denmark. Chip and Pin has been in Europe forever I don't think the US has moved to this yet (although happy to be wrong) and also believe they still like those bouncy checks that has sort of died elsewhere.

Also, they still expect you to authenticate when they phone you. No, I'm not going to tell you my birthday when you phone me. No wonder so many people get scammed, when banks are training people on how to get scammed.

When calling my bank I have to enter my entire CC number AND my PIN code.

Talk about training people to give away sensitive data.

I don’t think banks are deliberately trying to avoid using TOTP, it’s just that they have to cater to the lowest common denominator, you know, the kind for which anything computer-related is basically black magic. SMS is an easy target because ~everyone has a cell phone and with things like Apple’s verification code auto-complete, the amount of friction is greatly reduced. With standard TOTP, now they have to worry a…

This is no excuse for not offering it. And no, SMS must NOT be a backup that’s always available, as the article points out, its availability for use is a security hole.

If you can’t access your actual 2FA there should be an option for the bank to have it call that registered number and ask you “Hey this is (Bank). Are you trying to log in right now from Moscow on a Windows 10 PC using Firefox? If so, please call the number on the back of your card, hit 9, put in your SSN, then we’ll turn off 2FA for one login and let you add a new one. Btw if it is not you, your password is definitely compromised.”

Identity providing is a natural monopoly and should be provided by the state in same manner as a passport is provided. We can discuss the implementation but in Denmark and quite a few other countries, the login problem in online government services and banking is solved by a single state run identity provider (MitID) and hopefully the EU will be succesful with their EIDAS initiative and provide a solution that works…

In the U.S., identity providing is not a role the government fills. Not everyone has to have a passport, for example. A passport is merely a purpose-specific tool for crossing borders, not general identity.

Can we get rid of the password expiration too? Requiring that users change their perfectly secure password every 6 months is absurd and gives the impression of security when in reality it only makes things worse.

Banks are aware that NIST and various other bodies have updated their guidance about password expiration. Even vendors like Microsoft who supply extensively to financial services, have updated their guidance about password policies.

At this point — barring edge cases of operating in geographies where regulations haven’t caught up — it’s just inertia, aka “inaction doesn’t get you fired (usually)”.

> With standard TOTP, now they have to worry about if the user correctly added the secret

The standard flow I usually see for setting up TOTP ends with entering an authentication code. If it's not valid then the setup isn't finished.
