Meredith Whittaker reaffirms that Signal would leave UK if forced by privacy bill::Meredith Whittaker, the president of the Signal Foundation, the organization that maintains the Signal messaging app, spoke about the U.K.'s controversial new privacy bill at TC Disrupt 2023.
Why are you recommending people disable their Signal PINs? Best practice as far as I’m aware is to set a secure passphrase (rather than a 4 digit PIN) and to enable Registration Lock.
This article is the only one I was able to find with a recommendation that you opt out of setting a PIN, and even there they recognize that if you set a secure passphrase instead of a PIN, you aren’t reliant on SGX’s security anymore.
That article also doesn’t talk about how having a PIN is required to enable Registration Lock. Since Signal is dependent on phone numbers, disabling Registration Lock makes you vulnerable to account hijacking attacks. I would personally be more concerned about my contacts having their accounts hijacked - with the only indication of this on my end being that their Safety Number changed - than by them using a 4 digit PIN; if I were to recommend anything, it would be for them to use a secure passphrase (like an EFF dice-generated passphrase or a 12-word BIP39 phrase) and enable Registration Lock.
