Pro Tips
- The most common PINs (1234, 0000, 1111, 1234) are the first ones attackers try
- Never use birth year, address numbers, or phone numbers as PINs
- A random 4-digit PIN has 10,000 possibilities — not easily guessed in 3 tries
- For ATM PINs: most banks lock after 3 wrong attempts — random 4-digit is adequate
Frequently Asked Questions
Is a 4-digit PIN secure enough?
For physical devices with attempt limits (ATM = 3 tries, phone = 10 tries): yes, a random 4-digit PIN is adequate. For digital systems without limits: use 6+ digits or a full password instead.
What is the most common PIN?
1234 is used by ~11% of people, followed by 0000, 1111, and birth years. A random PIN avoids all these predictable patterns.
Should I use 6 digits instead of 4?
If the system supports it, yes. 6 digits (1 million combinations) is 100x harder to guess than 4 digits (10,000 combinations). iPhones support 6-digit passcodes.
How do I remember a random PIN?
Practice typing it 10-15 times when you first set it. Muscle memory develops quickly. Some people create a word from the phone keypad pattern (e.g., 2665 = "book").
