Executive summary
Context
Singpass Face Verification (SFV) enhances security for high-risk transactions such as setting up Singpass app and editing CPF withdrawal limits. However, high dropout rates and user complaints highlighted usability concerns. Before expanding SFV to more high-risk transactions, the design team urgently investigated user sentiments to identify critical design improvements.
Overall impact
Increased Face Verification success rates from ~80% to ~90%
Improved accessibility of Face Verification for visually impaired users and raised awareness of visually impaired users' challenges across product teams
Research objectives
We conducted user interviews with 15 users to learn more about:
How users feel about Singpass Face Verification (SFV)
How users feel about the need for extra authentication
What is the effectiveness and timeliness of our existing designs (i.e. messaging, content, illustrations)
Who we spoke to
Findings
7 out of 15 completed Singpass Face Verification
6 out of 15 did not complete
Due to
Mask covering mouth
Changes in facial features
Stuck while scanning face
2 out of 15 did not participate
Due to
Discomfort about face scanning
Overall experience
12 out of 15 participants expressed neutral-negative emotions.
“Surprisingly quite fast and easy.”
-P05
“Easy - just a little bit lengthy, but good because it’s 2nd layer of protection..”
-P06
“[It is] black & white, and flashing lights really put me off..”
-P14
“[I see Face Verification] I will bypass it, I will cancel the whole thing.”
-P04
Tackling concerns about Singpass Face Verification

Simplify do’s and don’ts to key points
Disclaimer: The updated animation was done by another designer.
9 out of 15 participants shared that not seeing their face was shocking. They hope to see their face while scanning as much as possible. Removing the filter also allows users to correct any lighting issues on the spot and increases probability of a successful scan.

Problem 2: Face Verification is not accessible for visually impaired users, leading to weekly escalated helpdesk tickets
Context
Visually impaired users struggled with Face Verification during Singpass app setup.
As sighted users, we struggled to understand why VI users faced challenges with Face Verification despite VoiceOver/TalkBack. To gain deeper insight, I collaborated with a GovTech Accessibility team colleague to organize a focus group discussion to empathise usability challenges better and learn more about workarounds.
Research method
I led a focus group with 5 visually impaired users with varying Face Verification experiences and outcomes.
Collaboration across teams
I rallied designers and product managers across Singpass devision to be sub-moderators in the session. This allows them to experience interviewing and working with visually-impaired users.
"My greatest takeaway is getting to see in real life how visually impaired users interact with SFV, it really requires a lot of patience." - Product manager of Singpass app
Usability gaps:
🤷♂️ Lack of precise audio feedback while scanning
😵💫 Scan starts too quickly — user moved while the scan is in progress.
Design solution
I proposed a audio feedback diagram to provide more guidance for visually impaired users.

We explored alternative login methods beyond Face Verification. Read more here.
