Calls on other internet firms to implement the new security technology.
Twitter has introduced new security measures that aims to make it more difficult to spy on users.
The micro-blogging site, which is calling on other Internet firms to do the same in a bid to prevent snooping by government intelligence agencies, has added has added an advanced layer of protection for HTTPS known as "forward secrecy."
In a statement, Twitter said: "A year and a half ago, Twitter was first served completely over HTTPS.
"Since then, it has become clearer and clearer how important that step was to protecting our users’ privacy.
"If an adversary is currently recording all Twitter users’ encrypted traffic, and they later crack or steal Twitter’s private keys, they should not be able to use those keys to decrypt the recorded traffic."
Forward secrecy prevents attackers from exploiting one potential weakness in HTTPS, which is that large quantities of data can be unscrambled if spies are able to steal a single private "key" that is then used to encrypt all the data, according to security expert Dan Kaminsky.
The latest move by Twitter comes in the wake of response from US Internet firms after revelations by Snowden regarding extensive US government surveillance programmes.
