What makes a PIN safe?
A PIN is a short number code. It can only be safe if the device or service locks you out after a few wrong tries —
and if the digits are random, not a birthday or 1234.
Like you’re 6: a PIN is the number code on your tablet. It’s safe because the tablet says “too many tries — go away!” after a few wrong guesses.
More digits, far fewer lucky guesses
Chance that a blind guesser opens it within 10 wrong tries (if the device allowed 10).
| Digits | Possible PINs | Chance in 10 tries |
|---|---|---|
| 4 digits | 10,000 | 1 in 1,000 |
| 6 digits | 1,000,000 | 1 in 100,000 |
| 8 digits | 100,000,000 | 1 in 10,000,000 |
| 10 digits | 10,000,000,000 | 1 in 1,000,000,000 |
Picking a PIN you can trust
Do
- Let the generator choose — people pick birthdays and patterns
- Use 6 digits (or more) wherever the device allows it
- Use a different PIN for your phone, bank card and door lock
- Make sure the device locks or wipes after a few wrong tries
Don’t
- 1234, 0000, 1111 or 2580 (straight down the keypad) — among the most guessed PINs
- Birthdays, anniversaries or the year you were born
- The same PIN as your bank card on your phone
- Using a PIN as an online account password
Need a password for a website or app account? Use a long random password or passphrase instead — a PIN is too short to protect an online login.
PIN questions, answered
Are PINs safe?
A PIN is only safe where a device or service limits wrong guesses — for example a phone that locks after a few tries or a bank card that is blocked. Without that limit, a short numeric code can be guessed quickly, so never use a PIN as an online password.
How many digits should a PIN have?
Use at least 6 digits wherever you can. A 4-digit PIN has only 10,000 possibilities; a 6-digit PIN has a million; 8 digits has a hundred million.
Is a random PIN better than one I choose?
Yes. People favour dates, repeats and keypad patterns, which attackers try first. A random PIN has no pattern to exploit.
Is my PIN sent anywhere?
No. It is created in your browser with a secure random generator and never sent to a server. It works in airplane mode.
