    The specific change you mention was a result of a security review we carried out on the OTP functionality. It is not good practice to provide methods to recover existing secrets because this makes it much easier to create cloned tokens that could be used without the knowledge of the original user to gain access to their account. Recovering OTP on an account by deleting the existing secret and creating a new one is more secure because even if it is done by the wrong person, the original user will realize the error the next time they try and log in using their old token.

    You see the same behaviour in most websites that offer OTP options like this - the only way to recover if you lose your OTP is to re-initialize with a new secret.

    Your point about including more specifics about this in the release notes is valid. We try to keep the release notes brief so that customers can read them all quickly and identify areas that may concern them where they can dig in to documentation to find out more. Sometimes we make them too brief. We'll take your feedback into account.

    [I updated my original post because I mistakenly thought I was reading the v19 EAP1 forum. Apologies for any confusion.]

    Running the Mac SpeedTest app (to a Cloudflare server, if that matters) fails during the upload phase. Sophos Application log indicates it thinks this is Torrent Clients P2P traffic. I can see how they might look alike, but..

    I think it's a combination of factors: sometimes Application Control is unhappy, sometimes it might be Intercept X, sometimes it might've been due to macOS Monterey (the SpeedTest app had a recent update), and sometimes it's Little Snitch stopping the app from contacting google analytics. Just throwing it out there that at least in two of the tests I got 4-5 errors logged in the firewall's Applications log. (This is running the latest MR2.)
