LessPass.com

Magical browser plugin/mobile app to make sure you have different password for different sites - enter the site name, username and master password, and you get the password. No syncing, no password uploaded.

Keybase.io

A site that make encryption available to everyday life. Drop me a secret hello message using Keybase.io now, and make it too to your friends. Keybase Chat is also worth trying, but it’s slower than Telegram due to their way to encrypt.

NOTICE Keybase.io might be slow or unavailable in China. You’d better to access it with special techniques in China.

Telegram

A messenger that is easy to use and privacy-first. Drop me a message, I’ve been here waiting for you long!

NOTICE Telegram is not accessible in China due to censorship. You’d better to access it with special techniques in China.
