• A password is like a secret word you type that a website remembers; if someone tricks you into telling it to them, they can pretend to be you.
• A passkey is more like a special key stored on your phone or computer that never leaves your device; the website only sees proof that your real key unlocked the door.
• Bad guys can steal or guess passwords using fake emails, keyloggers, or leaked databases, but they cannot copy your passkey because it stays locked inside your device.
• With passkeys, you usually just tap your fingerprint, look at your camera, or enter a short PIN, so it’s both easier and safer than remembering long, messy passwords.
• Until every site uses passkeys, you still need strong, unique passwords in a manager plus MFA, but the goal is to move toward passkeys and stop using passwords over time.
