We have already discussed two essential concepts. First, the passphrase, which is a useful replacement for traditional passwords. Second, hashing, which transforms a password into an unreadable fingerprint.
These two approaches are not mutually exclusive. In fact, they complement each other perfectly. By combining them, you can create a much more robust password security strategy. Here’s how.
Passphrases: memorable, but always unique
A passphrase is a complete sentence. It is often nonsensical, but easy to remember.
For example: “MyDogTakesTheTrainEverySundayMorningWithHisCoffee.”
Its length makes it difficult to guess. It is more resistant to brute force attacks. Yet it remains easy to remember.
But be careful: each account must have a different passphrase. Reusing the same phrase is like using a single key for all your doors. If one service is compromised, all your accounts are at risk.
Password managers: useful, but not perfect
It’s difficult to remember a different phrase for each site. That’s why password managers have become essential. They allow you to store, organize, and automatically fill in your login details.
This makes account management easier and faster. However, like any software, a manager can contain vulnerabilities. It can also be misconfigured or used on an infected device.
Even if it offers a good level of protection, it is not foolproof. That’s why an extra layer is highly recommended.
Salt and pepper hashing: an advanced security recipe
Adding salt or pepper to a password stored online or in a password manager strengthens its security against attacks, including dictionary and brute force attacks.
- Salt is a random value specific to each user, added to the password before hashing. It prevents attackers from using pre-calculated tables (such as rainbow tables) to guess passwords.
- Pepper, on the other hand, is a secret value that is shared but not stored with the passwords. It adds an extra layer of obfuscation.
Adding an unknown secret value makes the hash much more difficult to reverse.
This method requires a little discipline. But it offers a higher level of security, especially for critical access.
When to use what? The complete strategy
It’s not about choosing between passphrases, managers, or hashing. It’s about using them together, at the right time.
Here is a clear summary to guide you:
- Use a different passphrase for each account. It should be long, memorable, and unique.
- Store your passphrases in a password manager. This saves you from having to remember them all.
- Add a secret ingredient. This enhances security without relying on a third party.
- Check that websites use secure hashing. Avoid services that send your password back to you in plain text.
This way, you’ll be on the safe side. You’ll secure your access while keeping the method simple to apply.
