End-to-end encryption is any form of encryption in which only the sender and intended recipient can read the message. No third party, even the party providing the communication service, has knowledge of the encryption key. End-to-end encryption is the most secure form of encryption that you can use.
Take these actions to make sure you are as safe as you can be.
Use end-to-end encrypted apps
Switch to using messaging, email, and cloud apps that offer end-to-end encryption. Some are better than others, so make sure to read the reviews.
Turn on encryption on your devices or services
Some devices or services will offer encryption, but not set it as the default. Make sure to turn on encryption. Encryption can only be as good as the other security tools it relies on, so taking the following security steps are critical:
Use strong passwords
Do not just use a default password, a simple guessable password, or a password that uses personal information, e.g. your pet’s name. No matter how strongly your device or application is encrypted, if someone can figure out your password – they can access your data.
Keep up with updates
No system is perfectly secure. Security vulnerabilities are always being discovered and fixed with updates. That’s why it is so important to keep up with updates to your applications, devices and services. The update could be fixing a vulnerability and making you safer!
Turn on two-factor log-in (2FA)
Two-factor log-in adds another factor (like a bank security fob) to your usual log-in process (e.g. a username and password). Adding another factor makes it even harder for criminals to access your data.
Turn on erase-data options
Some smartphones and services have an option that will erase your data after 3 or 10 failed attempts. Turn this on to protect yourself from thieves or if you lose your phone.
