Password complexity rules
33 statesWhy it doesn't help
Length matters more than symbols. NIST, the federal standards agency, dropped composition rules in 2017. Long passwords and passphrases are harder to crack than short ones full of symbols.
What to say instead
Use a long (16+ characters), unique, randomly generated password or passphrase, stored in a password manager.
Avoid public Wi-Fi / use a VPN
30 statesWhy it doesn't help
Almost every website and app now encrypts its traffic, even on open networks. Large-scale attacks through public Wi-Fi are exceedingly rare. Personal VPNs add little for most people.
What to say instead
Public Wi-Fi is fine for everyday use. Keep devices and apps updated.
Change passwords regularly
28 statesWhy it doesn't help
There is no evidence that scheduled changes reduce crime. They lead people to pick weaker passwords and reuse them.
What to say instead
Change a password when there is reason to think it was exposed. Turn on multi-factor authentication.
Turn off Bluetooth / NFC
10 statesWhy it doesn't help
Wireless attacks in the wild are extraordinarily rare and need special hardware, physical proximity and a device that hasn't been updated.
What to say instead
Leave Bluetooth on if you use it. Keep devices updated.
Avoid public USB charging
9 statesWhy it doesn't help
There are no verified cases of juice jacking (malware or data theft through a public charging port) affecting everyday users. Phones ask before allowing data transfer.
What to say instead
Charge wherever you need to.
Clear cookies regularly
3 statesWhy it doesn't help
Clearing cookies doesn't meaningfully improve security, and it doesn't stop modern tracking.
What to say instead
Drop the advice. Spend the time on updates and multi-factor authentication.
