Singpass login is unsupported when I try to log in on another app (error code - AUTH-E0099). How can I log in?

Why am I seeing this error?


This app opens Singpass login in an embedded webview, which could compromise the security of your Singpass account.


Embedded webviews allow bad actors to intercept and modify communications between your device and Singpass, such as by:

  • inserting malicious scripts to record your activity

  • altering content of the webpage


Additionally, embedded webviews might not show the website’s address, making it difficult for you to verify whether you are actually logging into Singpass or a fraudulent phishing site.


What should I do next?

If you are seeing this error message AUTH-E0099, try accessing the service using a supported Internet browser (such as Chrome, Edge, Firefox, or Safari) by entering the web link in the address bar. In the event if your mobile browser does not work, read more about the supported browsers that support Singpass logins.
