Keeping your email and mobile number updated in Singpass helps ensure you don’t miss important updates and can access support when needed.

Here’s why we encourage you to do it:

Mobile Number

• Login & Security: Your mobile number is used for SMS Two-Factor Authentication (2FA) and you will receive your One-Time Passwords at the mobile number provided. It adds an extra layer of security to your account, especially when additional verification is needed.
  
  

• Transactional Alerts: You will receive an SMS notification when changes are made to your Singpass account, such as password change or reset. This helps you seek help quickly if the transaction is unauthorised.
  
  

• Support & Help: If you ever need help, we may use your registered number to reach you for troubleshooting or to verify your identity.
  
  

• Emergencies: In certain urgent or exceptional situations, it may be the only way for us to contact or assist you quickly.

Email Address

• Preferred Communication: If email is how you prefer to hear from us, keeping it up to date ensures you receive important service notices and updates.
  
  

• Access in Special Situations: In extenuating circumstances (like travelling or losing your phone), email may be used to verify your identity or recover access.
  
  

• Go Green: Email lets us reduce paper usage and move towards more sustainable, digital services.

We collect contact details to support secure login, respond to your queries, and help government agencies serve you effectively and safely. This is outlined in our Privacy Statement.
