Step Goal Time Core Questions & Probes
Prep (before call) Walk in knowing their context • Read their survey answers and product site.• Note current auth stack, team size, user base.
Welcome & framing Set tone, confidentiality 2 min “Thanks for taking the time! We’re researching real pain points with auth/login systems to guide a new open-source SDK. We’re not selling anything today—just learning. We’ll keep your input anonymous. OK to record?”
Role & product snapshot Establish relevance 5 min • “What’s your role day-to-day?”• “Give me the 30-second tour of your product & users.” * "What is the most critical personalized (i.e. requiring login) aspect of your product?"
Auth decision journey (Switch interview) Understand selection drivers & constraints (H3) 10 min 1. “When did you last choose or change an auth/login solution?”
  1. “What triggered that decision?”3. “Which options made the short-list? Why?”4. “Who had veto or final say?”5. “What did success look like?” (metrics, KPIs) | | Jobs-To-Be-Done & pain inventory | Unpack core/sub jobs, quantify pain (H1, H2) | 15 min | “Walk me through the ideal onboarding flow for a new user.”• Where does friction appear?• —dig for anecdotes & numbers:• First-time conversion (drop-offs, OAuth vs wallet)• Duplicate accounts / identity stitching (costs, support tickets)• Session continuity across channels/apps (wallet reconnects, SSO gaps)• Account recovery & customer support loadCompliance / security worries (KYC, 2FA, phishing) | | Life after integration | Reveal latent / ongoing headaches | 7 min | “Has your PM (or you) wanted to do something that wasn’t possible because of the account and login system? What was it and why was it blocked?” | | Cross-app & alias themes | Test hypotheses H4 & H5 (without pitching) | 12 min | 1.. Account merge: “How do you handle a user who signs up with Google, then connects a wallet, then Discord? What breaks?”

  2. “are there other apps that your customers use in their workflow with yours?” “How do they handle managing their identity and data across those apps?”

  3. Alias-based payments (email/phone → wallet): “Would something like ‘send funds to an email’ be valuable in your context? Why / why not?” | | Effort & willingness to switch | Gauge adoption barriers | 5 min | • “If a new SDK solved , how much dev time could you realistically invest to integrate it?” (days/weeks)• “Roughly what annual or MAU cost band feels acceptable?” | | Wrap-up & referrals | Close, incentive, snowball sampling | 4 min | • “Anything we didn’t ask but should have?”• “Who else (team or network) has strong views on auth we should talk to?”• Confirm incentive method; thank them. |
