You can change it in the app, yes.

I think you’ll have to reissue your ID.

There’s also digi-ID (similar e-signature certificate on a card, but without any ID features), Mobiil-ID (e-signature on a SIM-card, no idea how it works), Smart-ID (in app, tied to secure storage in Android/iOS, cross-signed by the server which is supposed to check the device somehow) and probably something else I don’t remember. All of these are independent options, so you can, for example, revoke your Mobiil-ID if you lose your phone, and still use the your main ID card to sign things.

Is the app tied to Google or Apple?

  • Nope, there’s a desktop version, too. And it’s all free/open source: https://github.com/open-eid

    (Though Smart-ID is its own thing and is a fair bit more locked down, but I’ve managed to get it running on a phone without Google services IIRC.)

    • Wow, that is definitely more sophisticated than we have in the states. It seems like you can use it for things that one would otherwise need a notary for, that is such a timesaver.

How much the certificate costs and lasts?

  • It costs as much as your ID card costs by the government, and lasts as long as well. They are one and the same. Applying for a new ID card / national ID document in Estonia costs 35€ and the document is valid for 5 years. If you forget your PIN code, you can reset it with your PUK codes, but if you also lose your PUK codes you need to apply for a new ID card. The process for getting a new ID card from the moment you applied for it takes no more than 30 days. You can also have it fast tracked for 250€ and get it in 2 days.

    But, like the parent said, you have many other options other than the physical ID-card as well. Most people these days use Mobiil-ID or SmartID, which works on your phone and even smart watch. SmartID is completely free and Mobiil-ID is tied to your phones carrier, so the cost varies, but it's a one-time set-up fee of around 5€. Mobiil-ID certificate also lasts 5 years.
