Why Passkeys, MFA and Strong Passphrases Matter More Than Ever

Phishing scams are more convincing. AI is making fake messages harder to spot. And once attackers get into one account, they often don’t stop there. They move laterally – email, banking, shopping, even identity data — turning a single mistake into something much bigger.

That’s how account takeovers become identity theft.

And the signals people used to rely on? They’re fading fast.

As James E. Lee, President of the Identity Theft Resource Center (ITRC), explains:
“Remember when we used to tell people bad spelling and poor grammar were the best way to tell if someone was trying to scam you or steal your identity? AI-assisted attacks now make it easy to convince people a scam is real, compromising or bypassing passwords along the way. That’s why we all need to change our habits to include a multi-layer approach to protecting our personal information, starting with passkeys where available, and long, unique passwords created by a password manager + MFA when passkeys are not available.”

The good news: protecting yourself doesn’t require expert-level skills. It requires a smarter, layered approach to how you log in; one that makes life harder for attackers, not for you. The new reality: passwords alone aren’t enough

Passwords are still everywhere. But on their own, they’re no longer strong enough to stand up to modern threats like phishing, credential stuffing, and data breaches.

Today, the most effective defense is layered:

• Strong, unique passphrases 
• A password manager 
• Multi-factor authentication (MFA) 
• Authenticator apps 
• Passkeys 

Each layer adds friction for attackers and resilience for you.

Start with stronger passwords or passphrases

Short, complex passwords are fading out. Long, unique passphrases are in.

A passphrase (something like a string of unrelated words) is:

• harder to crack 
• easier to remember 
• more resistant to brute-force attacks 

Aim for at least 12–15 characters and never reuse credentials across accounts.

Why? Because password reuse is one of the fastest paths to identity theft. One breached account can unlock many more—especially email, which acts as a gateway to everything else.

A password manager makes strong security a reality

Here’s the truth: no one can securely manage dozens of unique passwords on their own.

That’s where a password manager comes in. A tool like Norton Password Manager helps you:

• generate strong, unique passwords 
• store them securely 
• autofill them across devices 

👉 Instead of reusing passwords or writing them down, you create a system that scales safely.

And that matters because better password habits are one of the most effective ways to prevent account takeovers before they start.

MFA: the simplest upgrade with the biggest impact

Even strong passwords can be stolen through phishing, malware or breaches.

That’s why multi-factor authentication (MFA) is critical.

MFA requires a second form of verification:

• something you know (password) 
• something you have (device or app) 
• something you are (biometrics) 

So even if an attacker gets your password, they still hit a wall.

Think of it this way:
A password locks the door.
MFA adds a deadbolt.

Authenticator apps > SMS (and here’s why)

Many people rely on text message codes for MFA. It’s better than nothing—but it’s not the strongest option.

Authenticator apps are more secure because:

• codes are generated on your device 
• they aren’t transmitted over networks 
• they’re less vulnerable to SIM-swap attacks 

They also strike the right balance: strong security, minimal friction.

Passkeys: a simpler, phishing-resistant future

Passkeys are gaining traction for a reason. They remove the password entirely.

Instead of typing anything, you log in using:

• fingerprint 
• face scan 
• device PIN 

Behind the scenes, passkeys use public key cryptography, which means:

• no shared secrets to steal 
• no passwords to phish 
• no risk of entering credentials into fake sites 

They’re designed to be phishing-resistant by default.

Passkeys aren’t universal yet, but where they’re available, they’re one of the strongest upgrades you can make.

How account takeovers turn into identity theft

This is where it gets real.

When attackers access an account, they don’t just stop there. They:

• reset passwords 
• scrape personal data 
• impersonate you 
• pivot into financial or identity systems 

That’s how a compromised login becomes identity theft.

According to the Identity Theft Resource Center (ITRC), stolen credentials are one of the most common starting points for identity-related crimes. The U.S. Federal Trade Commission also notes that identity theft often begins with exposed login information.

In other words, protecting your accounts is one of the most effective ways to protect your identity.

Security doesn’t stop at login

Getting into your accounts safely is step one. What happens after matters too.

• Use secure apps with end-to-end encryption 
• Be cautious about what you share and store 
• Keep devices updated 

Good digital habits don’t end at login; they extend across everything you do online.

What to do now (start here)

Focus on your most important accounts:

• email 
• banking 
• shopping 
• social media 

Then:

• Create long, unique passphrases 
• Use a password manager  
• Turn on MFA everywhere you can 
• Choose an authenticator app over SMS 
• Adopt passkeys when available 

Build a layered defense that works

There’s no single fix for cybersecurity. The strongest protection comes from combining tools that reinforce each other:

• Passphrases protect against guessing and reuse 
• Password managers make strong habits sustainable 
• MFA blocks unauthorized access 
• Authenticator apps strengthen that layer 
• Passkeys reduce reliance on passwords entirely 

Build better sign-in habits, one step at a time

Together, they create a system that’s much harder to break—and much easier to live with. Attackers don’t need much, just one weak password, one reused login, one missed step. That’s why small upgrades matter. A stronger passphrase. Turning on MFA. Using a password manager. Choosing passkeys when you can.

You don’t have to do everything at once. But each step you take makes it harder for someone else to take control.
