Common mistakes to avoid
- Mot de passe trop simple (12345, motdepasse) : protection illusoire.
- Oublier le mot de passe : aucun moyen officiel de récupérer le document.
- Confondre protection en lecture et protection en modification.
Pro tips
- Utilisez un mot de passe d'au moins 12 caractères avec majuscules, chiffres et symboles.
- Stockez le mot de passe dans un gestionnaire dédié (1Password, Bitwarden, KeePass).
- Pour de la diffusion publique, exportez plutôt en PDF non modifiable.
Confidentiality guaranteed
Local processing. The password is never stored.
Password Protect a Word Document
Secure your sensitive DOCX files by adding an open password, directly in your browser. No data is transmitted to our servers, ensuring maximum confidentiality for your contracts, HR files, or strategic reports.
Microsoft Word Compatible Encryption
The applied password uses the standard encryption recognized by Microsoft Word. The recipient will need to enter the password before being able to open or view the document, wherever they are.
Choose a Robust Password
Opt for a password of at least 12 characters combining letters, numbers, and symbols. Without this password, the document is technically inaccessible, so keep it safe.
Total Confidentiality with Local Processing
Unlike conventional online services, our tool encrypts the document directly in your browser. The file and password never leave your device, eliminating any risk of leakage or interception.
No Uploads to Our Servers
Processing is done entirely client-side using JavaScript. Neither the document's content nor the password passes through our infrastructure: your confidentiality remains total.
Ideal for GDPR-Sensitive Documents
Personal data, contracts, medical records, or legal documents: all these contents can be protected without risk of GDPR violation, since nothing leaves your workstation.
Use Cases for Word Protection
Password protection is essential for sharing sensitive documents via email or a transfer service. It gives you control over access, even if the file is intercepted or transferred to an unauthorized third party.
Secure a Contract Before Sending
Communicate the contract to your client via email, and the password via another channel (SMS, call). This dual transmission method effectively protects your contractual agreements.
Protect a Confidential Company File
Commercial strategies, board meeting minutes, HR data: protect each internal document with a password before any sharing, even within your organization.
