Right, 1.0 might have been last year. But it was available (maybe called beta?) probably since 2018 at least. I have used Gitlab since 2018 and IIRC it had Turnstyle from the beginning. Gitlab have configured(?) it such that it comes at every login, but because it works automatically it has never been a problem for me. It wouldn't have worked on some phones, but I don't use phones for Gitlab.

I wasn't aware that they have (had) alternative solutions. Probably because I've rarely seen them. Or if they used reCAPTCHA I got mad on Google, not noticing that Cloudflare had injected it.
