Time for #DevDiscuss — right here on DEV 😎
Inspired by @dagnelies's Top 7 post, tonight’s topic is...passwordless authentication!
Questions:
- Is passwordless authentication the future, a big mistake, or somewhere in between?
- Have you implemented passwordless authentication in any of your applications? What tools did you use, and how did it work?
- What pitfalls, traps, and flaws should devs be aware of when implementing passwordless auth?
- Do you have any stories of passwordless triumphs and/or fails?

I'd say very much yes that passwords probably are this really funny "early days of computers" thing that won't stick around usefully longterm.
The problem is that we are sort of in an extended hellish in between of all the different ways to authenticate, and we might be that way for a while.
I think the right authentication for the future has to be sort of an abstraction over all the different stuff that came before it, and I don't know if we're there yet.
Just discovered passwordless.dev/ recently acquired by Bitwarden.
Commercial providers are popping up more and more lately. They noticed too the breakthrough that WebAuthn provides and now race for market share and early adopters. Here are some: passageid, hanko, ownid, corbado, orysh, cisco... And bigger auth providers like auth0/okta, onelogin and others are stepping up too.
Nevertheless, as far as I know, Passwordless.ID is the only one which attempts to make a free public identity provider, which is crazy enough in itself.
Hum, makes sense. Thank you @dagnelies ! Was not aware of that. In any case, it's probably the sign of a deep-rooted trend.
For me, it's a good choice to avoid accounts hacked with a normal credential email + password. This is very simple and securised.
Got a private key like a SSH key, is just awesome ✨
I'm using some websites who using just email, and you do check your email to click on the link and validate is you. That is the one of better way to authentification! 🙌
it's called "magic links," and it's quite handy, but you have to be careful with the implementation. Otherwise, it can be vulnerable.
Oh thanks for telling me what it was called. I couldn't remember. 😆👍🏼
And yes, like all systems, we must be careful indeed
Indeed, but this one is quite critical. I was thinking as a dev who has to implement it. While there are some cons, you'd better use libraries in this case.
I've seen live projects where you can inject parameters in the URL, or with non-expiring tokens. These projects had memberships and payments associated.
Outch 🙁

Passwordless authentication via WebAuthn is a powerful, secure, easy, useful, and outstanding way to authenticate.
It is easier on your users. They love not hunting up, creating, and dealing with passwords. Registering is as easy as a FaceID or a fingerprint. So is logging in.
Companies like mine make it really easy to implement. So easy, it is hard to convince developers that it really is that easy.
It's way, way, way more secure. I liken the threat surface of passkeys to a small puddle, where passwords have the threat surface of Lake Michigan.
I don't see how passwords are used at all at some point in the future. Hopefully the near future. ;-)
As a lifelong Michigander, I appreciate your analogy 😁
Passkeys finally look like a usable and safe (by synching the passkeys between devices) way to do passwordless auth.
It's a bit too early for passkeys but at least applications could propose WebAuthn as a compliment to passwords for now.
Passkeys absolutely are intended to be the winner here, and because passkeys are now possible in iOS and, I believe at least in Chrome Canary/Beta, I think that this is the time to start progressively enhancing registration/login flows to work alongside passwords for now and eventually replace them.
The syncing part of passkeys is cool, but we do need to get users used to it, as well as used to the QR code method of using a passkey across device when syncing isn't available. There might be some short term user experience degradation as people figure that out, but once we're over that passwords can be buried
That's an interesting topic, I'll stick around.
I want to apply passwordless into a project but further developments on other projects are consuming my time (and my soul 😂) so I don't think it will be till march when I'm able to start the given side-project, and the info shared here can be quite useful!
I like to use public/private keys (e.g., ssh), which can be considered as a passwordless auth.
This one is easy to set.
I don't understand password less authentication. Firebase offers it but I don't see the benefit of signing into your emails to sign into another site. Seems like it adds more friction.
I see why having email and password are sometimes bad but do we not use email/ password to get into our emails? So our app is secure but what if someone gets into our emails?
Are we not just passing the email password issues over to our email provider?
Try the demo in the article, no email nor password necessary. It's about passwordless authentication using fingerprint, face, swipe pattern or any local device authentication for the web. ;)
In that case I'm all for fingerprint/ face unlocking but I don't understand firebases passwordless solution. What are your thoughts?
A user clicks a link in their emails to login to another website
It's thrilling to see this discussion going on! If you ask me, passwordless authentication is certainly the future, without a doubt, as it is both way more secure and much more convenient for the user ...but there are hurdles and it's only half the story.
The hurdle is that the specification itself is very complex, making it challenging for developers and adoption slower. Moreover, it requires re-thinking authentication procedures since only registered devices can authenticate (*). Lastly, the user experience may vary depending on device/OS/browser and it is new and unfamiliar concept for users too. Nevertheless, I think it's just a question of time until it becomes the default login option for the MS, Google, Apple accounts.
This brings us to the second half of the story. In the long term, people would be annoyed to re-register their multiple devices for various websites, or call the account recovery procedure just because they bought a new phone. And that is what lead to the so-called "passkeys". (*) It is the same protocol, the same access keys, but they (MS, Google, Apple) will synchronize your keys accross all your devices. Sounds great, right, but also note that it is a weakening of the protocol since the keys are not so secret anymore.
Now, if you think even further ahead, I think it will lead to a kind of user aquisition war. I mean, you can either (passwordlessly) sign in accross all android devices or all windows devices or all apple devices, but not mix them, except if the website goes the extra mile to support it. Binding the user's access keys to the platform is kind of binding the user itself.
The only alternative to that is a platform neutral identity provider. That way, your credentials would not be bound to the platform and would be a central place to manage all allowed devices for all apps at once. I guess you see where I'm heading to, that's exactly what Passwordless.ID is meant to be.
I'd say it's one-part marketing gimmick, and 2 parts evolving the consumer end of authentication to reflect the state of technology we have at our disposal.
This may sound arrogant or crass but I'm going to say yes as the concepts of Passwordless authentication aren't new. SAML for example will federate authentication without a password.
Broadly speaking - be aware that Auth as a mature feature is not a small effort. Building your own user/password auth is a good exercise for learning, but not something you necessarily want to scale & maintain for the next 10 years. I avoid building my own auth these days, instead favoring third-parties like Auth0 or Okta.
No stories, but I'll take the opportunity to give 1Password a shout out. They're an awesome product as a User for password management, and I'm loving their solution for managing and deploying secrets across my environments. The developer experience working with them has been awesome!
I struggle keeping track of all my passwords and different 2FAs and making sure i don’t fall into the habit of reusing a password because i can’t be bothered to think of a new one 🥴😅
I personally now use a password manager and have it on my phone and pc as I’m not a fan of the apple “suggest password “ because by the time it pops up with remember password, it’s refreshed and it’s gone forever 😂
Having apps use touch or Face ID was a game changer so I’m always interested in the next thing to help with this but keeping skeptical as to making sure my passwords are secure.
