IF COMPLEX!
A PASSWORD MANAGER CAN HELP!
CAN BE HARD TO GUESS( BY SOMEONE) IF COMPLEX!
BUT DO USE PASSWORD MANAGER SO YOU DON'T FORGET!
1234
A pincode
NOT SO HARD TO GUESS
OFTEN COMBINED WITH THE MAXIMUM ALLOWED NUMBER OF ATTEMPTS!
FAIRLY EASY TO REMEMBER

ONE TIME PASSWORDS
Valid for one-time use
Often expire after a certain time
Sent directly to the user
SENT IN SMS
iOS and Android let you fill in the OTP with the press of a button
NOT ALL TELECOM OPERATORS TAKE SECURITY SERIOUS, SMS MESSAGES CAN BE INTERCEBTED
You need your cellphone on hand
SENT IN AN EMAIL
You don't need a second device
EMAILS CAN BE INTERCEPTED
AUTHENTICATOR APP
SOCIAL
ONE LESS PASSWORD TO REMEMBER
ONLY GIVE PASSWORDS TO A SERVICE YOU TRUST
YOU RELY ON ANOTHER SERVICE FOR YOUR AUTHENTICATION
OFTEN USED AS A SECOND FACTOR
SO HOW'S YOUR PASSWORD SHOULD BE?
