But what if you need to change the phone number itself? As of today, you can change your number in Telegram — and keep <strong>everything</strong>, including <strong>all</strong> your contacts, messages and media from the Telegram cloud, as well as all your secret chats.</p> <div><center> <a href="../file/811140130/1/tCTi6Uk4zsg/c75df0be1059e2d727.png" target="_blank"><img src="../file/811140130/1/tCTi6Uk4zsg/c75df0be1059e2d727.png" title="Tap on your number in Setings" style="padding: 20px; width: 200px" /></a> <a href="../file/811140000/1/o0mRniLoPYc/3fafe3a6d666588353.png" target="_blank"><img src="../file/811140000/1/o0mRniLoPYc/3fafe3a6d666588353.png" title="Then tap 'Change Number'" style="padding: 20px; width: 200px" /></a> </center> </div> <p>Your mutual contacts (people in your contacts, who also have your number) will get your new number added to your contact in their address book unless you have blocked them in Telegram. This makes changing numbers even easier.</p> <h4><a class="anchor" name="perfect-forward-secrecy" href="#perfect-forward-secrecy"><i class="anchor-icon"></i></a>Perfect Forward Secrecy</h4> <p>Last but not least, Telegram's Secret Chats now support <a href="http://en.wikipedia.org/wiki/Forward_secrecy">Perfect Forward Secrecy</a>. What this means is that your Secret Chats will now automatically <a href="https://core.telegram.org/api/end-to-end/pfs">change encryption keys</a> after a period of time, in order to keep past communications safe. This way you no longer need to manually re-create Secret Chats to achieve this level of security.</p> <div><br></div> <p>And that's it for today.
