telegram:
- very good android, ios, and desktop open-source apps they keep properly up to date (also a web client)
- stickers, emojos, gifs (and with better compression)
- useful bots (and inline bots)
- groups and good admin tools
- nicely including voice or video in chats
- now even favorites
- requires a phone number (not public)
- is not very secure (but above average)
- is centralized and not entirely open (they haven't been evil for now)
the security:
- decent c/s transport encryption (yes, good https still is a noticeable point)
- functional and easy to use 2FA (and enabled by default i think)
- session management
- local passcode
- account self-destruct function
- optional "last seen"
- half-assed end-to-end encryption (that kinda works okay afaik, but it's limited to 1:1 private chats and surely could be designed cleaner and better)
@CobaltVelvet 2FA isn't on by default unless they changed it recently, you need to manually set it up under Privacy and Security > 2-Step Verification
