This means that we should pick our password more carefully. We can’t just use the old method of selecting password, because it take less and less time to crack a password using today’s tool and computing resources
Here are some password tips
- Randomly substitute numbers for letters that look similar. The letter ‘o’ becomes the number ’0′, or even better an ‘@’ or ‘*’. (i.e. – P@ssw0rd)
- Randomly upper-case some letters (i.e. – 3iLveRciTy)
- Think of something related to your childhood.
- Don’t choose a word or person’s name from the dictionary.
- Choose a place you loved, or a specific place, an attraction from a vacation, or a favorite dish in your favourite restaurant?
- You really need to have different username / password combinations for everything. Don’t try to use the same password everywhere.
