In this case, it's what you do when signing in from a new device (or browser) to attest that it's yours. It avoids warnings to you and your contacts that a device has gained access to your account without your approval.

It involves doing one of these things:

- Comparing a short sequence of emoji on each device and confirming that they match.

- Using one device to scan a QR code displayed by the other.

- Entering a recovery key (a line of text) that you were given when you first set up the account.

Pretty quick and easy in most cases, although some clients can be glitchy in this area and require trying again.

(Gripe: The recovery key approach was unfortunately made painful and error-prone in recent Element releases, by disabling the option to choose a passphrase instead, but most people can simply use one of the other two approaches.)

Maybe I’m missing something but why does this service need this process while Discord or whatever don’t?

The experiences reported here seem to say otherwise...

As others, anyhow, I haven't tried again recently

I last tried Element about six months ago, but for years using the recovery key was either impossible or close to it, and mostly just for idiotic UI mistakes that were never corrected (something like you had to enter the key where they wanted the passphrase or the opposite).

To my recollection the version from six months ago worked better in that regard, but it was still asking to enter the passphrase where you actually had to enter the recovery key.

		I think current Element versions accept either a recovery key or recovery passphrase in the same input field, so there's no getting it wrong. Since you seem focused on UI, it's worth noting that Element X (their beta mobile app) has a greatly simplified interface; their team clearly has been working to make it easier. Also, other clients exist. For whatever it's worth, I've been using Matrix for about five years, including some of its roughest times. I seldom see errors these days, but I can understand how folks who were frustrated with earlier iterations would still be soured to it. Such is the nature of an ambitious work in progress, I suppose. I use it because there is nothing else with the combination of features that are most important to me, and because (despite my gripes) I can see slow and steady improvement. I think it's moving in the right direction overall. I could picture introducing family members to it once Matrix 2.0 is released and the implementations shake out any early problems.
