The problem people are complaining about
On 2026-10-21, a thread titled “IPhone 17 passkeys not working” reached #28 in our daily ranking of tech support problems on Reddit. In tech support, people most often struggle with broken Windows installs, phones that won't charge, slow PCs, networking glitches and account lockouts; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what Passkey Doctor aims at.
Who the customer is
Consumers whose passkeys fail across devices, and small SaaS teams rolling out passkey login who need to support confused users.
In short, the first customer to target is: Consumers and small IT teams adopting passkeys. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
Passkey Doctor is a content + b2b consulting idea. A troubleshooting hub and test page that checks passkey support across devices and walks users through fixes. It makes money through ads/affiliate (password managers); paid passkey rollout audits for small SaaS companies.

| Difficulty | Med |
| Opportunity score | 6/10 — Growing topic as passwords phase out; B2B angle is the real money. |
Pricing guess
Estimate: free consumer guides; $500-2,000 per passkey rollout audit for small SaaS companies. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Weekend: WebAuthn test page + fixes for top 10 errors. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Publish a WebAuthn test page and fixes for the top errors; measure traffic.
- Offer three free audits to small SaaS companies in exchange for testimonials.
- Track which errors users report most.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
passkeys.dev, vendor docs, 1Password/Bitwarden help centres Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Platform vendors keep changing behaviour.
- Consumer side monetises poorly.
- B2B sales take time.
How we scored it
Opportunity score (6/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (2/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
