Usually you shouldn't share passwords, but if you have to for some reason, this is the way to do it. It also allows 2FA to be shared/updated on multiple devices at the same time.

Amazing to see authenticated encryption get standardized in OpenPGP. I wrote an opt-in AES_GCM mode for OpenPGP.js using native WebCrypto in 2016 and never thought it would get through since the GPG devs didn’t like GCM. Congrats @BartCButler & team!

#Ukraine: Overnight, Ukrainian USVs (Kamikaze Sea Drones) attacked the Russian port of Novorossiysk, hitting the "Olenegorsky Gornyk" Project 775 large landing ship of the Russian navy- causing it to list due to internal flooding.
The full extent of the damage is so far unclear.

Lol the Twitter webapp is trying to load something from its internal graphql API and getting a 429 Too Many Requests response. Twitter's Javascript ignores the error and tries again, hundreds of times a second.
Twitter is DDOSing itself.

Welcome @Apple! Affirming the longstanding expert consensus:
Encryption works for all or it’s broken for all. There’s no safe, private way to conduct mass surveillance. & no amount of magical thinking or specious claims will alter this stubborn reality.
