Encrypted archives are often used for contracts, scans, exports, or accounting files sent by email. The weak point is usually not the archive format. It is the password: too short, reused, or sent in the same message as the file.
Qsen’s password generator lets you create a separate password for the archive and choose a length that is strong enough without making the recipient struggle to type it.
Choose a practical length
For a one-time document archive, avoid four- or six-character passwords. They are convenient but too easy to guess. A practical starting point is a random password of 14–16 characters. For more sensitive files, use a longer one.
If the recipient will type the password on a phone, keep readability in mind. Avoid confusing characters where possible, or use a longer passphrase. Do not replace randomness with obvious words, company names, or dates.
Share the password through a separate channel
Do not send the archive and password in the same email. If the message is forwarded or exposed, the protection becomes mostly symbolic. Send the file by email and the password through another channel such as a messenger, SMS, phone call, or approved internal system.
Teams should have a simple rule: the password never travels next to the file, the archive name does not contain it, and old archive passwords are not reused.
A simple work scenario
You need to send a partner a set of closing documents. First, create the archive. Then generate a new password and apply it to the archive. Attach the file to the email and write: “I will send the password separately.” After the email is sent, share the password through the agreed channel.
This gives the recipient clear expectations and gives your team a repeatable process.
Mistakes to avoid
- using the same password as an email or work account;
- reusing one archive password for every partner;
- putting the password in the email subject;
- building it from the company name and year;
- sending the archive without opening it once yourself.
Before sending, open the archive on your own device and confirm that the password works.
FAQ
Can I use one password for the same partner every time?
It is safer not to. If that password is leaked once, every archive using it becomes easier to access.
Are special characters required?
They help, but only if the recipient can type them correctly. A longer random password is often better than a short, awkward one.
Where should the password be stored?
Use a password manager or approved secure storage if you need to keep it. Avoid plain spreadsheets or chat history as the only record.
