As other services are currently under SMS attack, we will also stop all SMS transmissions outside the EU, EEA and Switzerland in productive operation for the time being and thus also the sending of so-called One Time Codes via SMS. Other methods such as Passkey, Mobile ID App, Signature Approval App are still available.
Hint: only non-EU/CH/EEA mobile numbers are affected. Roaming customers are not affected if they use their domestic mobile number e.g. in Asia or Africa.
