Telegram is giving away FREE Premium subscriptions! All they need from you is to use your cell phone as a relay to text out their OTP codes! And the recipient of the OTP sees your phone number! What could POSSIBLY go wrong with this deal?
PLEASE don’t use Telegram! I personally recommend Matrix as it’s totally FOSS, you can self host, there are tons of front end clients to choose from. Or even use Signal. I have my own issues with Signal, the fact they don’t allow third party clients, you can’t self-host, they have a proprietary shim in their stack that only they know what it does, they were pushing crypto, etc, but at least Signal is better than this garbage.
Even Thunderbird does XMPP… There’s also conversejs and xmpp-web for browsers and a bunch of others for specific platforms. This video has a good explanation of the XMPP architecture and usefulness.
Here’s the thing XMPP is great as a protocol and as a concept, unfortunately the clients don’t seem to be following up on times really well, but with a bit of patience you can get things to work, even push notifications.
Thats a really informative video. Thanks
