Common uses:

• Two-factor authentication (2FA): A temporary code sent to your phone or email that you enter along with your username and password
• Site access codes: Some private or restricted websites require a passcode to enter (like employee portals or exclusive content areas)
• Parental controls: Age-restricted content may require a passcode to verify you’re old enough to access it
• Premium features: Some sites use passcodes to unlock paid or special content
• Password reset: Temporary codes sent to verify your identity when resetting your password

How they work:

• Usually numeric (though some may include letters)
• Often time-sensitive and expire after a few minutes
• May be sent via SMS, email, or generated by an authenticator app
• Typically shorter and simpler than full passwords

Difference from passwords:

• Passcodes are usually shorter and numeric-only
• Often temporary rather than permanent
• Used as a second layer of security rather than the primary login method
