FILE SHARING GUIDE
Password-Protected File Sharing
A share link is convenient because it gives someone direct access to a transfer. Password protection adds another step: even if somebody receives the link, they still need the correct password before accessing the protected transfer.
What does password protection do?
When a transfer is password protected, the recipient must enter the password chosen by the sender before gaining access to the shared files.
This can be useful if the share link is accidentally forwarded, copied into the wrong conversation, or seen by somebody who was not meant to receive the files.
When should you use a password?
Not every transfer needs a password. A casual collection of photos being sent to a friend may not need the same protection as work documents or files intended for a specific recipient.
Password protection may be useful for:
• Client or business documents
• Private photos or videos
• Project files intended for a limited group
• Documents containing non-public information
• Transfers sent through shared communication channels
• Files that should not open from the link alone
A password does not make every file safe to share
Password protection is an additional access control, not a reason to upload information that should never be placed on a file-sharing service.
Before uploading anything sensitive, consider whether online file sharing is appropriate for that content. You remain responsible for deciding what files you upload and who should receive them.
Choose a password that is difficult to guess
Avoid obvious passwords such as a person's first name, the word "password," a simple number sequence, or information that somebody could easily guess.
A longer password or passphrase that combines unrelated words, numbers, or symbols is generally harder to guess than a very short password.
Better password habits:
• Use something unique for the transfer.
• Avoid common words by themselves.
• Avoid personal information others may know.
• Prefer a longer password or passphrase.
• Do not reuse an important account password.
Send the password separately when appropriate
If you send the share link and password together in the exact same message, anyone who gains access to that message may receive both pieces of information.
For transfers that need stronger separation, you can send the link through one channel and provide the password separately. For example, send the link by email and the password by text message.
Password protection and link expiration work together
A password controls access while the transfer is active. Expiration controls how long the transfer is intended to remain available.
Using both can be useful because the recipient needs the password during the active period, while the link is also designed to stop being usable after its expiration window.

A QR code can make a share link convenient to open, but anyone who can see the QR code may be able to scan it. Password protection can add another step before the shared files are accessible.
Avoid displaying a QR code publicly if the transfer itself is intended for only a small private group.

A folder may contain many different files, so review the entire folder before sharing it. Password protection applies to access to the transfer, but you should still make sure every included file is appropriate for the intended recipient.
This is particularly important when folders contain a mix of personal photos, work documents, screenshots, or other files accumulated over time.

Registered JustSeconds users can use password protection for eligible transfers. When creating the transfer, enable password protection and choose the password that recipients will need to enter.
Once the upload finishes, send the generated share link to the intended recipient and provide the password separately when appropriate.
Password-protected sharing checklist
✓ Confirm the correct files are in the transfer.
✓ Choose a password that is not easy to guess.
✓ Do not reuse an important account password.
✓ Send the password separately when appropriate.
✓ Check when the transfer will expire.
✓ Keep your own copy of important files.
Frequently asked questions
Does password protection hide the share link?
No. The link can still be copied or forwarded. Password protection adds a required access step before the protected transfer can be opened.
Should I send the password in the same email as the link?
You can, but for transfers that need stronger separation, sending the password through a different communication channel can reduce the chance that one exposed message reveals both the link and password.
Does a password stop the recipient from sharing the file?
No. Once somebody legitimately downloads a file, they may be able to copy or redistribute that downloaded file. Password protection controls access to the transfer; it does not control a downloaded copy afterward.
Does the recipient need a JustSeconds account?
A recipient normally does not need an account to open an active share link. For a password-protected transfer, they also need the password selected by the sender.
