What are the most common weak PINs to avoid?

The most common PINs are: 1234, 0000, 1111, 1212, 7777, 1004, 2000, 4444, 2222, 6969. Any PIN based on a birth year, anniversary, or sequential/repeated digits is also significantly weaker than random.

Is a 4-digit PIN secure enough?

A 4-digit PIN has only 10,000 possible combinations. It is acceptable for low-stakes applications (gym locker, basic device lock) but inadequate for banking or high-value access. Use 6+ digits for anything sensitive.

Can I use letters in a PIN?

Traditional PINs are numeric only. If your system allows alphanumeric codes, use the full password generator instead — a 6-character alphanumeric code has 56 billion+ combinations versus 1 million for a 6-digit numeric PIN.

Generate a Strong PIN Code

A random PIN is far more secure than one based on birthdays, anniversaries, or sequential numbers. FixTools generates cryptographically random PIN codes of any length — 4, 6, or 8 digits — for bank cards, phones, safes, and any PIN-protected system.

How to use this tool

💡

Choose your PIN length (4, 6, or 8 digits) and click Generate for a cryptographically random PIN code.

How It Works

Step-by-step guide to generate a strong pin code:

1
Choose your PIN length
Select 4 digits (basic), 6 digits (recommended for phones and banking apps), or 8 digits (high-security applications).
2
Generate the PIN
Click Generate. The PIN is created using cryptographic randomness — not a simple formula.
3
Check it isn't a common PIN
The generator avoids the most common weak PINs automatically. Confirm your PIN does not visually form a keyboard pattern.
4
Memorise or store securely
Memorise the PIN if possible. If you must record it, store it as an encrypted note in your password manager — never write it on or near the device it protects.

Real-world examples

Common situations where this approach makes a real difference:

New bank card activation

A customer activating a new bank card generates a random 4-digit PIN instead of using their birth year or a sequential number. They memorise it and store it as a secure note in their password manager as a backup.

Phone screen lock

A user setting up a new phone generates a 6-digit random PIN for their screen lock, replacing the 1234 PIN they had used on their previous phone.

Safe combination

An office manager setting a new PIN for the office safe generates an 8-digit random combination and records it in the company's secure vault rather than choosing an easily guessable date.

When to use this guide

Use this when setting a new PIN for a bank card, mobile phone, safe, door lock, or any system that uses a numeric PIN for access control.

Pro tips

Get better results with these expert suggestions:

Avoid PINs based on personal dates

Birthdays, anniversaries, and years are the first combinations attackers and thieves try. A random PIN that has no personal connection is significantly more secure.

Use 6 digits wherever possible

A 6-digit PIN has 1,000,000 combinations — 100x more than a 4-digit PIN's 10,000. Most modern phones, banking apps, and security devices support 6-digit PINs.

Memorise the PIN — do not write it on the card or near the device

Writing a PIN on a bank card or sticky note attached to the safe completely defeats the security of the PIN. Memorise it or store it in a password manager as a note.
