Linked services
A linked external service is a fast, password-free sign-in: press the bank or Yandex button, confirm — and you're in your profile. You manage the links on the «Security» screen, in the «Linked services and banks» section.
What you can do here
The section shows which services are already connected to your profile: «Sberbank Business ID», «Alfa ID», «T-Bank ID» and «Yandex ID», each with a state — «Linked» or «Not linked». A connected one has an «Unlink» button next to it; a free one has «Link».
A link doesn't replace your usual sign-in by phone — it adds to it. Your phone, password and passkeys stay in place; a linked service simply gives you one more way in.
How to link a service
- Open the «Security» screen and find the «Linked services and banks» section.
- Click «Link» next to the service you want.
- You're taken to the service itself — confirm access there.
- You come back to your profile, and the service appears in the linked list.
After that you can sign in to Invoicebox ID through it without a password.
How to unlink
Click «Unlink» next to a service — the link is removed at once, in a single click. You won't be able to sign in through that service until you link it again. Your other sign-in methods keep working.
Warning
Don't unlink your only way in. If you sign in only through an external service, first set a password or add a passkey — otherwise you risk losing access to your profile.
What's next
- Strengthen your sign-in with other methods: two-factor protection and passkeys.
- Check which apps are connected to your profile in the App access section.
If a service won't link or something unfamiliar shows up in the list, write to c-support@invoicebox.ru or call +7 (812) 448-08-01 (9:00–21:00 Moscow time).
