Data breaches can occur when text files containing sensitive information are not properly protected. Text files often store private information, including personal messages and confidential business documents.
Protect texts with a private message box
Sometimes you need to share private information within a text file but want to restrict access to certain portions. Using a private message box tool can help in this situation. PrivNote is one of the most popular online services that lets you paste text into a private note. You then generate a unique secret link to share access to that note. The link expires after a certain period or number of views.
The note data passes through the browser before reaching PrivNote’s servers. It prevents the PrivNote service from accessing the private information in the note. Anyone with the secret link views the note in their browser but PrivNote deletes it once it expires or reaches the view limit. You also password-protect private notes for an extra layer of security. It allows real-time encrypted conversations plus you send encrypted files up to 5GB in size. Like PrivNote, Salamander lets you control access with expiring message links or message passwords. The zero-knowledge encryption ensures your data stays private from third parties.
Use a local encrypted notes app
Sometimes your notes only need to be private locally on your own devices. In this case, an encrypted notes app better protects your text files and messages stored on your phone or computer. Private local apps like Standard Notes, Joplin, and Boostnote are great options for securely taking notes, writing documents, or saving bits of information long-term. The apps allow you to create end-to-end encrypted notes private to you. Any text you type into the app only be decrypted on devices where you set up the app. The apps also have features like biometric authentication, passcode locks, and automatic encryption for added security. Some even allow you to enable self-destructing notes and media after some time. Don’t forget to back up your encryption keys in case you need to restore your data. Also, enable sync across devices to access your private notes anywhere. It is important to note that the notes are only encrypted locally, not when they are synchronized.
Use strong passphrases
No matter which apps or services you use to store and share private text files, always protect them with strong, unique passphrases. Use long passwords or phrases that are difficult to guess. Use random words, numbers, and symbols to create a long password.
how to protect text file with password? Passphrases can be set up and stored using a password manager like LastPass or 1Password. It helps avoid password reuse which compromises security. Two-factor authentication should also be enabled. With 2FA, you’ll enter your master password and then receive a second code through an authenticator app or SMS to full login.
Enable the highest resolution settings possible for your device’s screen lock too. It ensures someone can’t simply glance at your screen to read your private messages. Strong passphrases and device lock security provide the foundation for data security.
