No I've never seen this. Usually they send you an email to the admin address of the domain with the code.

What is the TLD of the domain you're trying to move? Not all registrars support all domain names. For example .ie domains for Ireland can only be registered at very few registrars, which is a pain.

Off the top of my head, OVH might fulfill your needs, depending on the TLD.

I've transferred domains out of porkbun without seeing anything like that. I've had to release the domain lock and paste a transfer authorization code from one place to another. That's how it has worked at other registrars too.

Lol, what did you try to register? downwithdomainnameregistrars.com?

I use porkbun, they seem great, why are you switching? Just to have a European based registrar?

Since your goal is "to move to a European registrar" Porkbun is not for you.

I suggest you reach out to Infomaniak support and ask for an alternative method which is less invasive.

Try to make Infomaniak a better experience for everyone. Infomaniak claims to be "The Ethical Cloud" but they did not start business as a privacy company and have been learning over time. Help to teach them with one more customer story. Let us know what happens.

If no luck with Infomaniak helping, you can try to contact a different registrar before signing up to confirm they will accept your domain type and ask them what the process will be. Hold them accountable to whatever process they describe if you choose them.

Yes, this is normal. The alternative is having your domain stolen and held ransom by someone who pretends to be you. Usually they do have an alternative method though, using some other 2fa like a yubikey.

Not normal at all. Go a different (more reputable) registrar.

Cloudflare is my permanent goto.

Gandi (gandi.net) is based in France. While I’m currently not using them, I have in the past and had a positive experience.

It depends on the registrar. Some just assume the information you provided is valid.
Infomaniak apparently wants to verify your info, though they also offered verification through credit card when I signed up.

Some tlds require the owner to meet some legal requirements, like affiliation with a specific country. I've registered .us domains before without requests for ID but I did pay with a US based card.
