Sign in with a passkey, Google or Smart-ID

Oct 23, 2026

You can now sign in to Sliptree with a passkey or with your Google account, so there is one less password to remember and type. In Estonia, Latvia and Lithuania you can also sign up with Smart-ID, Mobile-ID or an ID card, and use them to get back into your account when nothing else works.

Sign in with a passkey

A passkey uses your device's fingerprint, face or PIN instead of a password, and a fake website cannot trick you into giving it away. On the sign-in page, click Sign in with a passkey, or pick your passkey from the suggestions that appear in the email field. If you use two-factor authentication, a passkey sign-in needs no code, because the passkey on your device already is the second step.

After you sign in with a password, Sliptree offers to add a passkey, and you can also add one at any time in your Profile. The new Sign-in section there lists your passkeys and holds the password form too. Read more about your profile and account security.

Sign in or sign up with Google

Continue with Google is now on the sign-in and sign-up pages, so you can sign in with your Google account or create a new Sliptree account with it. If your Sliptree account uses the same Gmail or Google Workspace address, Google signs you straight into it. To use a Google account with a different address, connect it in the Sign-in section of your Profile.

Sliptree now emails you when a passkey is added or removed, when Google is connected or disconnected, and when an ID code is linked to your account, so you notice a change you did not make.

Smart-ID, Mobile-ID and ID card in Estonia, Latvia and Lithuania

If you are in one of the three Baltic countries, or use Sliptree in Estonian, Latvian or Lithuanian, the sign-up page now starts with Smart-ID, Mobile-ID or ID card. You verify your identity in a window on the page and pick your company, and Sliptree fills in its details from the business register. Then you add your email address and a passkey or a password. Your identity is already verified, so when you turn on e-invoicing later, that check is done.

The same way in also helps when you cannot sign in. Below the sign-in form, click Can't sign in? and verify your identity. Your ID code is linked to your account if you signed up this way or verified your identity for e-invoicing. In that case Sliptree signs you in and asks you to add a passkey or set a new password.

Joining a company that is already on Sliptree

A company can now be in Sliptree only once. When you add a company whose registry code another account already uses, you ask that account's owner for access instead of making a second copy. If the business register says you can represent the company, click Ask for access. The owner gets an email, and if they do not answer within 7 days, you get admin rights automatically. Anyone else can click Send join request, and the owner decides. Owners see both kinds of request on the Members page. They approve or decline a join request, and they can approve an access request before its date.
