If you still have access to the old phone or to your authenticator app: go to Account, remove the registered device and add a new one.
If you have lost access ΓÇö a replaced or wiped phone, an authenticator app that was not restored ΓÇö there are two routes.
If you have Google or Microsoft connected to your account, sign in that way. It does not require your Sigill one-time code. Once you are in, go to Account, remove the old two-factor device and register a new one. This is by far the quickest route, and a good reason to connect one of them before you need it.
Otherwise, ask an administrator at your organisation. Under Users they can reset your password and two-factor authentication together. Your old device stops working immediately, and you are emailed a link to choose a new password and enrol a new authenticator. No one ΓÇö not your administrator, not us ΓÇö sees your password at any point.
If that email does not arrive, you are not stuck: sign in with your existing password ΓÇö the old one-time code is no longer asked for ΓÇö and you will be prompted to set a new password and enrol a new authenticator right there.
If there is no administrator who can help ΓÇö you are the only one, or you have lost access to the account that holds the role ΓÇö contact support@sigill.tech. We will verify who you are and reset it for you.
You cannot restore it entirely on your own, because signing in requires the code you no longer have. Note also that resetting only your password does not help ΓÇö a one-time code is still required afterwards, which is why the reset covers both.
To avoid the situation altogether: register your authenticator in an app that syncs across your devices, or store the setup key somewhere safe when you first configure it.
