# **How to Create a Strong Password**

Weak passwords are one of the most common causes of hacked accounts. The good news: with the right approach, you can protect your accounts reliably — without memorising complicated strings of characters.

## What Makes a Password Strong?

A strong password has high **entropy** — a measure of its randomness and unpredictability. The higher the entropy, the longer it takes an attacker to crack it.

Key factors that increase security:

- **Length**: Every additional character multiplies the number of possible combinations exponentially
- **Character variety**: Uppercase and lowercase letters, digits, and symbols expand the character space
- **Randomness**: No dictionary words, no patterns like "1234" or "qwerty"

## Common Mistakes to Avoid

### Personal information

Birthdates, pet names, or favourite sports teams are easy to guess — especially if your social media profiles are public.

### Reusing passwords

When a website is breached, attackers immediately try compromised credentials on other services (known as "credential stuffing"). Every account needs a unique password.

### Patterns instead of randomness

`**Password123!**` technically meets most requirements — but attackers know these patterns and test them first.

## Three Proven Methods

### 1. Classic random password

A password generated with `**crypto.getRandomValues()**` consisting of 20+ characters with uppercase and lowercase letters, digits, and symbols has over 130 bits of entropy. That translates to billions of years of cracking time — even with modern hardware.

Example: `**nX7!kQr3mVp9wL2$jY8t**`

### 2. Passphrase (Diceware)

A passphrase made of 5–6 randomly chosen words is often more secure than a short complex password — and far easier to remember.

Example: `**tiger-atlas-flower-window-coffee**`

With 5 words from a 7,776-word list, you get over 64 bits of entropy. Passphrases are explicitly recommended by security experts including NIST.

### 3. Use a password manager

The easiest path to strong passwords: a password manager (e.g. Bitwarden, 1Password, KeePass) generates and stores a unique, strong password for every account. You only need to remember one master password.

## Understanding Entropy

| **Method** | **Characters/Words** | **Entropy** |
| --- | --- | --- |
| 8-char classic | 8 | \~52 bits |
| 12-char classic | 12 | \~78 bits |
| 20-char classic | 20 | \~130 bits |
| 4-word passphrase | 4 | \~51 bits |
| 5-word passphrase | 5 | \~64 bits |
| 6-word passphrase | 6 | \~77 bits |

As a rule of thumb: **at least 60 bits** for regular accounts, **80+ bits** for important accounts like email and banking.
