Earlier quoted context omitted.

The current US administration is known for illegally deporting permanent residents and has stated intent to deport natural-born citizens. It should be self-evident why a centralized ID system under the control of the executive branch is a terrible idea.

That's horrible but why would it be worse together with an e-id system?

Because without thoroughly-enshrined protections for identities, an e-ID system provides an avenue for the government to effectively de-person undesirables at will, by removing their ability to use banks, sign contracts, access healthcare, etc.

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 n…

Why would a bank care about money laundering?

Because look at what happens when the government thinks you don't care enough about money laundering. TD Bank recently got hit with a $3 billion fine.

> More than 90% of transactions went unmonitored between January 2018 to April 2024, which “enabled three money laundering networks to collectively transfer more than $670 million through TD Bank accounts,” according to a legal filing.

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.

> they still expect you to authenticate when they phone you Why has some startup not solved this problem already?

Authentication is not one problem with one solution.

It is many problems with many solutions.

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…

Absolutely not! The moment you have universal state-issued identity, you will be expected to provide it for everything , including tons of stuff that doesn’t require identity. Don’t be a privacy defeatist, the fight isn’t lost yet. Resist every single effort to make it easier for merchants and private entities to strongly identify users. The rows go into databases and they never go away. State-issued identity is one…

The way identity providers are supposed to work is to not necessarily divulge your identity, but properties necessary for the respective service. For example, they can attest that you are an adult and a citizen of $country, but don’t need to disclose any further information. When using an identity provider with a third-party service, the attested attributes are displayed to the user to approve their disclosure. This is a bit like app permissions, where you can specify which app should be able to have which permission.

Passkeys = excellent UX? In what world is that? I keep looking st them, see the fragmentation, and have to say "no thanks, great idea, horrible reality".

If you store them in a password manager it is pretty nice, but if not it can be pretty cumbersome, especially if using browsers with multiple profiles.

I had someone ask for my name. I told them my first and last name. They said it wasn't correct. After a few minutes of discussion, it turns out the person wanted my name as it appeared on my card , which is first name, middle initial, last name and a suffix. I told the person as feedback that what they asked for and what they wanted were two different things. I'm not optimistic that anything will change.

It will improve once we have AI smarter than agents who work for the wages banks pay for this.

The weakness is in the processes and the lack of critical thinking skills of people executing processes.

The entire debt collection ecosystem works like this as well. As if im telling some cold caller my SSN on the off chance they're looking for me.

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)”.

It's not inertia. In my big corpo's case, it's because the cybersecurity insurer is refusing to follow NIST.

Excellent UX and security. In response to the complaints about SMS MFA, yeah, it has its issues (we don't even support it in our auth software) but it's not totally indefensible. It makes i…

> People really don't understand passkeys

Passkey UX is absolutely terrible. It's unclear what is happening, what is being stored where (do you have my passkey? do I? is it in my browser? is it on my phone?), how communication is happening between devices, etc. Also nobody seems to explain what exactly a passkey is. Where's the thing I can point at and say "that's your passkey"?
