10 Key Metrics for Achieving Optimal SEO Results

The shift from passwords to attribute-based access

Ever tried logging into a retail app you haven't used in months only to realize you forgot the password and now you're stuck in "password reset hell"? It's honestly the worst, and for most businesses, it’s where they lose customers for good.

Passwords are basically the "leaky bucket" of the internet. We keep trying to patch them, but they just don't work for modern Customer Identity and Access Management (CIAM) because humans are terrible at them. We reuse the same ones everywhere, which is a goldmine for hackers.

• Credential stuffing is a plague: Since people use the same password for their bank and their favorite pizza shop, one breach at a small site can compromise their whole digital life.
• Support costs are a silent killer: I've seen companies spend a fortune just paying helpdesk staff to click "reset" for frustrated users.
• Trust disappears fast: According to the Verizon 2024 Data Breach Investigations Report, about 68% of breaches involved a non-privileged human element, like falling for phishing or just using weak passwords.

"The most secure password is the one you never have to remember. (The most secure password is one you don't have to remember)"

So, if we ditch the password, what's left? We start looking at identity attributes. This is the shift toward using what a user has or is instead of just what they memorize.

It’s not just about your name or email anymore. We’re talking about behavioral signals—like how you hold your phone—and device metadata. When you use passkeys, the "identity" is tied to a physical device and a biometric check, making it way harder to fake.

In healthcare, this might mean a patient accessing records via a face scan on their trusted phone, while in finance, it’s checking if the login api is coming from a known ip address. Of course, ip checks are just "signals" and not absolute proof since hackers can spoof them, so we usually weight them against biometrics or "continuous auth" to be safe. It's much more fluid than a clunky text box.

Next, we'll dig into how these specific attributes actually get collected without creeping out your users.

Managing consumer profile data without the friction

Ever wonder why we're still filling out 10-field signup forms like it’s 1998? It’s the fastest way to kill your conversion rate, honestly. If I have to tell a retail app my middle name and zip code just to buy a pair of socks, I’m probably just gonna close the tab.

This is where tools like mojoauth come in handy for us devs. Instead of building a massive database to store hashed passwords (and worrying about the next big leak), you just drop in a bit of javascript. It handles the heavy lifting of identity attributes without the headache.

When a user signs up, they don't "create" an account in the old sense. They just verify who they are—maybe through a magic link or a passkey. You get the verified email attribute, and the user gets in without hitting a wall.

// quick example of how you'd init a login
const mojoauth = new MojoAuth("YOUR_API_KEY");

mojoauth.signIn().then(response => {
  if (response.authenticated) {
    // the response object is populated after the magic link/passkey flow
    console.log("User email verified:", response.user.email);
    // now we can start building their profile slowly
  }
});

The trick is progressive profiling. You don't need their life story on day one. Start with the bare minimum—an email or a phone number—and ask for more as they actually need to use those features.

• Biometrics are the goat: Using a thumbprint or face scan to verify an attribute is way smoother than a captcha. It proves "you are you" without making the user do work.
• Context matters: If someone is logging in from a new device in a different country, that's an attribute you should check.
• Don't be a data hoarder: Only ask for what you need. A 2023 report by PwC showed that 82% of consumers are way more likely to share personal info if they actually trust how the company handles it.

In a healthcare app, you might let someone browse doctors with just an email, but ask for insurance details only when they book the appointment. It keeps the "front door" wide open while keeping the sensitive stuff locked down.

Next, we’re gonna look at the dark side—how hackers try to break these systems and how we stop them.

Threat landscape and breach prevention in passwordless

So we got rid of passwords, which is great, but don't go thinking the hackers just packed up and went home. They just changed their playbook—now they're after the "session" or the recovery flow instead of your dog's name followed by 123.

If there isn't a password to phish, the bad guys try to steal the "active" session. This is session hijacking, where they grab the browser cookie after you've already done the biometric dance. It's like someone sneaking into your house through the window after you've already unlocked the front door.

Social engineering hasn't gone away either; it just moved to the "help, I lost my phone" desk. If your account recovery is just a support agent reset, that’s a massive hole. A 2023 report by Microsoft highlights how token theft is becoming a go-to for attackers bypassing mfa.

• MFA is still a thing: Even without passwords, you want layers. Maybe a passkey plus a "known device" check.
• Continuous auth: Don't just check the identity at login. If the ip address jumps from New York to London in five minutes, something is wrong.
• Recovery is the weak link: Use "identity proofing" (like scanning a real ID) for recovery instead of just a "secret question" about your first car.

When you move to attribute-based access, you’re storing things like biometric hashes or device IDs. If that data leaks, it’s way worse than a password breach because people can't exactly change their fingerprints.

Encryption at rest is the bare minimum, but you also gotta shield the api that handles this data. If your api isn't rate-limited or properly scoped, a bot could scrap a whole database of user attributes without ever needing a "login."

In retail, a breach of profile data might mean leaked shopping habits, which is creepy but not fatal. But in finance or healthcare, those attributes are the keys to the kingdom. We need to stop thinking about "securing the account" and start thinking about "securing the data stream."

Next, we’re gonna wrap up with some best practices for protocols and how to handle privacy without losing your mind.

Best practices for iam engineers and developers

So, you’ve ditched the passwords. Congrats, you’re already ahead of most people, but now you gotta actually manage all these identity attributes without breaking everything or getting sued. It's a lot to juggle, honestly.

When you're picking a protocol, don't just grab whatever looks shiny. Fido2 and webauthn are the gold standard because they use hardware-backed security, but if your users are on older tech, you might still need magic links as a fallback.

If you're sharing attributes across different apps, oidc (OpenID Connect) is your best friend. It lets you pass "claims"—basically bits of user data—securely between systems.

Migrating legacy data is usually where the headaches start. You can't just "import" biometrics from another system. You have to wait for the user to log in once with their old credentials, then "trap" them into registering a passkey.

Decentralized identity is coming, and it's gonna change how we think about "owning" data. Instead of you holding a database of birthdays, the user holds a "verifiable credential" in their digital wallet and just shares a proof with your api.

And yeah, we have to talk about privacy. A 2023 report by Deloitte - which discusses how privacy-first designs build long-term brand value - notes that being transparent about data is basically a competitive advantage now. If you're compliant with gdpr or ccpa, you aren't just avoiding fines; you're building trust.

ai is also starting to play a huge role in identity. In the future, your system might not just check a thumbprint; it'll analyze the "risk score" of the entire login attempt in real-time.

At the end of the day, just keep it simple. Only collect the attributes you actually need to provide the service. Your users will thank you, and your legal team will sleep way better at night.
