corresponding numbers.

For this example, you can easily mentally calculate this password with a few steps :

1. Remember the single digit you chose. Here it is 1.
2. Spell it. Here, it will be O – N – E.
3. Take the first letter and convert it into a number. Here, it will be 0 (Zero).
4. Spell that number found in Step 3. Here, it will be Z – E – R – O
5. Replace the first letter with the corresponding special character. Here it is ‘!’
6. Replace letters with corresponding numbers wherever applicable.
7. Now you have got ‘!3r0’. Type it immediately.
8. Go back to Step 3 and apply the same for the second (N) and third (E) letters of O  – N – E

How to secure passwords?

• Do not share your password with anyone.
• Do not write down or store your password in unsafe places.
• Please keep your secret algorithm secret.
• Change your password occasionally. Changing the input of your secret algorithm would do the trick.
• Enable 2-step verification if possible.
