To effectively approach a 50–80% passkey adoption threshold, enterprises should focus on several influential passkey best practices that have demonstrated consistent success in real-world deployments:

• Immediate Post-Login Nudges: Prompt users to create passkeys directly after successful login, as this timing leverages users’ authentication mindset and significantly increases enrollment rates.
• Contextual Messaging: Emphasize clear user benefits—convenience ("Faster logins without passwords") or security ("Protect your account from phishing")—based on user segments.

• Automatic Enrollment on Mobile: Automatically triggering biometric-based passkey enrollment on mobile devices typically increases adoption by 30–50%.
• Manual Enrollment on Desktop: Allow desktop users explicit control, using manual prompts to avoid intrusive experiences.

Transition gradually from voluntary adoption to mandatory enforcement. Clearly communicate timelines and benefits well in advance, such as "Passwords will be phased out next month—set up your passkey today."

Encourage users who have set up passkeys on one device to extend this practice across additional devices. Example prompt: "Add a passkey to this device to avoid passwords next time."

Continuously test and optimize messaging and UX flows across various demographics, device types, and operating systems. Identify which prompts generate the highest user responsiveness.

6. Analytics & KPI Monitoring

• Track crucial metrics including:
  • Passkey Acceptance Rate (responsiveness to prompts)
  • Passkey Creation Success Rate (completed enrollments)
  • Number of Created Passkeys (growth over time)
• Use these insights to fine-tune passkey strategies and reduce user friction.

By combining these passkey best practices, enterprises can systematically drive user adoption toward the critical 50–80% threshold, substantially improving security, reducing reliance on passwords, and enhancing user satisfaction.
