# Passkeys for User Retention: Why Keychain keeps Customers

## Key Facts

- **iCloud Keychain and Google Password Manager** sync passkeys automatically, so
  credentials persist across device upgrades and app reinstalls without any user action.
- **Passkeys cannot be forgotten** unlike passwords, reducing re-login to a single
  biometric step and eliminating password reset flows for returning users.
- Nearly **99%+ of mobile OS share** is passkey-capable, meaning the vast majority of
  smartphone users can benefit from synced credential managers today.
- **Cookie-based re-engagement** is weakening: the CJEU Planet49 ruling requires active
  consent and Apple's Intelligent Tracking Prevention blocks third-party cookies.
- **Conditional UI** presents saved passkeys as a native autofill dropdown, reducing
  re-login friction for returning users even after long gaps between visits.

## 1. Introduction: Keep your Customers with Passkeys in their Keychain

**Passkeys are becoming the default way consumers sign in**. Stored in
[iCloud Keychain](https://www.corbado.com/glossary/icloud-keychain) or
[Google Password Manager](https://www.corbado.com/blog/how-to-use-google-password-manager), they **persist across
device upgrades** and make returning sign-in effortless.

For growth teams, that creates a new retention lever: **once a passkey is saved, re-login
friction collapses** to a single biometric step.

## 2. Passkeys live in Credential Managers

Nearly every smartphone is passkey-capable
([99%+ mobile OS share](https://gs.statcounter.com/os-market-share/mobile/worldwide)).
Passkeys are [digital credentials](https://www.corbado.com/blog/digital-credentials-api) tied to a user account
and saved in platform credential managers or third-party password managers.

From the data that we observe across the general industry most of the passkeys are stored
in the credential managers from Apple, Google and Microsoft. Only a very small fraction
uses dedicated third-party credential managers (then, mostly by tech-savvy users).

Let's focus on Apple (iOS, macOS) and [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android)
devices as their default credential manager syncs passkeys per default. Windows devices
still have no syncable credential manager onboard as of January 2026. This is expected to
change soon, so that also Windows users can benefit from the accessibility of synced
passkeys. Today, these users would need to store their
[passkeys in Google](https://www.corbado.com/blog/google-passkeys)
[Password Manager](https://www.corbado.com/blog/passkeys-vs-password-managers) (via Chrome on Windows) or in
3rd-party password managers, such as
[1Password](https://www.corbado.com/blog/1password-passkeys-best-practices-analysis).

### 2.1 iOS/macOS: iCloud Keychain + Passwords App

On Apple devices, passkeys sync per default via
[iCloud Keychain](https://www.corbado.com/glossary/icloud-keychain) and appear in the Passwords app. Users rarely
delete them manually.

### 2.2 Android/Chrome: Google Password Manager

On [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android) and Chrome, passkeys sync via
[Google Password Manager](https://www.corbado.com/blog/how-to-use-google-password-manager). Google has also
enabled passkey sync across Windows and macOS, expanding cross-platform reach.
[Samsung](https://www.corbado.com/blog/samsung-passkeys) [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android) devices
often uses the [Samsung](https://www.corbado.com/blog/samsung-passkeys) Pass app as the default credential
manager though.

## 3. Why Cookie-Era Re-Engagement is weakening

In recent decades, cookies played a crucial role for business-to-consumer (B2C) companies,
allowing them to personalize the user experience with user-related information in websites
and apps, such as storefront preferences for a single buyer. Enabling features such as
adding items to shopping carts, saved preferences and user account information, they were
essential for facilitating [e-commerce](https://www.corbado.com/passkeys-for-e-commerce) transactions.

However, several developments have weakened cookie-based re-engagement:

### 3.1 Cookie Consent Requirements

The requirement for active opt-in consent for non-essential cookies was established by the
[CJEU Planet49 ruling (C-673/17)](https://curia.europa.eu/juris/liste.jsf?num=C-673/17) in
October 2019, later reaffirmed by Germany's Federal Court (BGH) in May 2020. Websites must
now provide clear information about the cookies they use, their purposes and obtain active
consent before setting non-essential cookies.

### 3.2 Safari/WebKit blocks Third-Party Cookies

Apple's **Intelligent Tracking Prevention (ITP)** blocks many third-party cookies,
limiting cross-site tracking and protecting
[user privacy](https://www.corbado.com/faq/ensure-gdpr-compliance-with-passkeys).

### 3.3 Chrome: Third-Party Cookies - what actually happened (updated 2026)

Chrome tested restrictions and explored changes, but Google later announced Chrome will
**keep its current approach to third-party cookie choice** and
[won't roll out a new standalone prompt](https://privacysandbox.com/news/privacy-sandbox-next-steps/).
Meanwhile, Safari/WebKit has long had strong tracking prevention.

These limitations make clear that cookie-based re-engagement is less dependable, so
getting users to easily log in matters now even more.

## 4. Passkey Retention Loop

Passkeys stored in credential managers that **sync across devices** (e.g.
[iCloud Keychain](https://www.corbado.com/glossary/icloud-keychain),
[Google Password Manager](https://www.corbado.com/blog/how-to-use-google-password-manager)) are a powerful tool
for user retention. The "cost" of a user returning after weeks or months drops
dramatically compared to password-based authentication, as passkeys cannot be forgotten
(unlike passwords) and only very few users delete them manually.

### 4.1 No Password Resets

Users are reminded which email they signed up with (if it's a usernameless login via
[Conditional UI](https://www.corbado.com/glossary/conditional-ui) or 1-tap passkey buttons). Moreover, they don't
need to remember a password. Thus, they also don't need to hit
[password reset](https://www.corbado.com/blog/password-reset-increase-customer-retention) flows again.

### 4.2 Native Autofill Experience

[Conditional UI](https://www.corbado.com/glossary/conditional-ui) presents available passkey in a convenient
dropdown. Re-login UX feels like a native autofill, even after months of returning to a
site. Features like 1-tap passkey buttons provide very similar experience and can this
reduce friction further.

### 4.3 Device Upgrade Continuity

Users switching between phones or flipping browsers keep access to their passkeys if they
keep the same credential manager. This is another benefit and reduces
[cart abandonment](https://www.corbado.com/blog/ecommerce-authentication) and churn, directly increasing
conversion.

### 4.4 Passkeys Persist until deleted

Even after [iOS](https://www.corbado.com/blog/webauthn-errors) / Android app uninstalls, passkeys remain in the
credential manager. This allows a seamless login after a re-installation without
remembering a password (or username).

## 5. Growth Playbook: Get a Passkey into the Keychain

The key takeaway is that a [synced passkey](https://www.corbado.com/blog/device-bound-synced-passkeys) stored in
a credential manager makes reactivation cheap. For detailed implementation strategies, see
our [passkey creation](https://www.corbado.com/blog/passkey-creation-best-practices) best practices and
[passkey login](https://www.corbado.com/blog/passkey-login-best-practices) best practices guides.

### 5.1 Best Moments to Prompt Passkey Creation

Timing matters for [passkey user prompts](https://www.corbado.com/faq/passkey-user-prompts-increase-adoption).
The three highest-conversion moments:

1. **After successful conventional login**: this is where the trust is just established
   and the user is engaged. Promote the passkey by making the next login even simpler and
   quicker.
2. **After checkout**: this is a high-intent moment and the user may want to return easily
   for future purchases.

### 5.2 One-Click Account Creation with Passkeys

Email (or in general a username) and a quick biometric scan (e.g.
[Face ID](https://www.corbado.com/faq/is-face-id-passkey), Touch ID or the Android biometric equivalent) is all
that's required for creating an account. There's no password needed. These simple
requirements have also the potential to convert
[guest checkout](https://www.corbado.com/blog/guest-checkout-vs-forced-login) users to accounts faster and
increases your passkey coverage from day one.

### 5.3 Keep Fallback Paths

Not all users want to immediately
[transition to passkeys](https://www.corbado.com/blog/user-transition-passkeys-expert-strategies) or they might
be on non-passkey-ready device. That's why it's important to keep a password or magic link
fallback. A broken sign-in flow destroys retention gains. See
[fallback management](https://www.corbado.com/faq/fallback-management-user-trust-passkey-retention) strategies
for implementation details.

## 6. How Corbado can help

Implementing passkeys is one thing. Understanding how they impact your retention metrics
is another. Corbado provides comprehensive
[authentication analytics](https://www.corbado.com/blog/authentication-analytics-playbook) and observability out
of the box:

### 6.1 Passkey Analytics Dashboard

Track the metrics that matter for user retention:

- **Passkey activation rate**: What's teh share of users who have created at least one
  passkey
- **Login success rate**: How often passkey logins succeed vs. how often fallback methods
  like passwords succeed
- **Time-to-auth**: How fast can users complete their sign-in process with passkeys vs.
  other methods like passwords

### 6.2 Device and Platform Insights

Understand [passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case) across your user base:

- Breakdown by OS (iOS, Android, Windows, macOS)
- Browser compatibility insights
- Credential manager distribution (iCloud Keychain vs. Google Password Manager)

This observability helps growth teams **prove ROI** and identify optimization
opportunities in the
[passkey retention](https://www.corbado.com/faq/fallback-management-user-trust-passkey-retention) loop. For a
deeper dive into passkey-specific metrics, see our

across all methods, see the
[authentication analytics](https://www.corbado.com/blog/authentication-analytics-playbook) playbook.

## 7. Conclusion

Passkeys present a powerful way to improve user retention by storing credentials in iCloud
Keychain or Google Password Manager where they persist and sync across devices. They offer
an alternative to cookie-era re-engagement, improving UX while increasing sign-up,
re-login and retention rates.

But implementing passkeys without analytics is flying blind. Corbado's solution gives you
the observability to measure impact: track
[passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case), monitor re-login rates and prove
retention improvements with real data.
