If your OneKey token is low in battery or out of battery, you may wish to use SMS 2FA if your service provider (e.g., SingPass) offers this option. If you are using OneKey token to access SingPass, we encourage you to download and use SingPass Mobile app for a more convenient login. This also allows you to avoid the S$15 token replacement fee.
