Gestionnaires de mots de passe, expliqués aux personnes normales
24 juin 2026 · 2 min de lecture · Commentaires
Il vous suffit de mémoriser un seul mot de passe. Voici comment fonctionnent les gestionnaires de mots de passe, pourquoi ils sont plus sûrs que ce que vous faites actuellement et lequel choisir.
Le problème de la façon dont la plupart des gens gèrent les mots de passe
- The average person reuses the same 2–3 passwords across dozens of sites. When one site gets hacked — and they do, constantly — attackers try those same passwords everywhere else. This is called a credential stuffing attack.
- In 2024 alone, over 10 billion unique login credentials were leaked in a single database dump.
- The solution is a unique, strong password for every site. The problem is that's impossible to remember. That's exactly what a password manager solves.

Comment fonctionne un gestionnaire de mots de passe
- You create one strong master password. The password manager uses that to encrypt a vault containing all your other passwords.
- When you visit a site, it automatically fills in the correct username and password. You never type or remember it.
- When you create a new account, it generates a random, unguessable password (e.g.
xK9#mPqL2$vNrY7j) and saves it immediately. - Your vault is encrypted on your device before it's synced to the cloud. Even the company can't read your passwords.
Lequel devriez-vous utiliser ?
- Bitwarden is our top pick. It's open-source (anyone can audit the code), has a generous free tier, works on every device and browser, and costs €10/year for premium features you probably don't need yet.
- 1Password is polished and family-friendly, but costs €3/month. Worth it if you want to share passwords with a partner or household.
- Apple Keychain is built into every iPhone and Mac. If you never use Windows or Android, it works perfectly and costs nothing.
Comment commencer
- Install Bitwarden and create an account. Pick a strong master password you'll actually remember — something like a phrase from a song plus a number and symbol.
- Install the browser extension. From now on, every time you log into a site, Bitwarden will offer to save the password. Say yes.
- Over the next few weeks, as you naturally log into your accounts, Bitwarden builds your vault. You don't need to do it all at once.
