A master password protects every other password stored in your password manager.
It must be secure, unique, and memorable enough to recall without writing it down in plain text.
This method provides a reliable way to create one.

Step 1: Write a Sentence You Can Remember
Create a long, personal sentence that has meaning only to you.
The sentence should be:
- At least 8–12 words.
- Based on a real memory, habit, quote, or event.
- Something you can visualize clearly.
Examples
- “The school I graduated from was located in Boston Massachusetts in 1991.”
- “My first apartment was on the 3rd floor of 214 Pine Street in 2002!”
- “I drink black coffee before 8AM or I turn into a pumpkin.”
Step 2: Convert It Into an Acronym
Take the first letter of each word.
Preserve capital letters, numbers, and punctuation.
This transforms your sentence into a compact, high-entropy string that’s still easy to recall if you remember the original story.
Example
“My first apartment was on the 3rd floor of 214 Pine Street in 2002!”

Step 3: (Bonus) Add Minor Customization
Apply a private, consistent rule that only you know.
This increases complexity without reducing memorability.
Common examples:
- Replace certain letters with symbols: a → @, i → !, s → $.
- Add a symbol at a fixed position (e.g., always insert # after the 3rd character).
These adjustments add entropy and make it harder for an attacker to guess even if they suspect your method.
Step 4: Check Length and Variation
Ensure your master password:
- Is at least 14 characters long.
- Contains uppercase and lowercase letters, numbers, and symbols.
- Does not reuse parts of other passwords.
- Is used only for your password manager.
Step 5: Store a Hint (Not the Password)
Write a short hint to help you recall the original sentence.
Store it securely — in a notebook, encrypted drive, or in someone else’s password manager.
Example Hint: “First apartment 2002, Pine Street.”
Never write down the actual password in full. With exception when using 1Password Emergency Recovery Kit.
Why This Works
- Tough to guess: Each sentence produces a random-looking string that’s long and unpredictable.
- Unique: It’s tied to your personal memory, not a public phrase.
- Memorable: You remember the story, not the symbols.
- Secure: Resistant to brute-force and dictionary attacks because the pattern isn’t guessable.
