Meta's introduction of passkeys for Facebook on Android and iOS devices, announced on June 18, 2025, leverages FIDO Alliance technology to replace passwords with biometric authentication or device PINs.
Unlike passwords, passkeys are cryptographic keys stored on users' devices, making them resistant to phishing attacks that trick users into revealing credentials on fake websites.
The Verge notes that passkeys link to specific domains, preventing activation on fraudulent pages, a critical defense against the 68% rise in phishing attacks reported by Zscaler in 2024.
However, the Electronic Frontier Foundation warns that users who fall back on passwords for non-mobile logins remain vulnerable, as passwords can still be entered on phishing sites.
Meta assures that biometric data, such as fingerprints or facial scans, stays on the device and is never shared, addressing privacy concerns. Yet, the system's effectiveness hinges on user adoption; only 12% of global internet users employed passkeys by mid-2025, per a Thales report, suggesting a slow transition that leaves many exposed to traditional threats.

Will Device Dependency Create New Risks?
Passkeys require physical access to a compatible device, a strength that TechCrunch highlights as a barrier to remote hacking attempts. This device-centric model eliminates the risk of password leaks, which affected 2.6 billion personal records in 2024, according to a Surfshark study.
However, the dependency on devices introduces challenges; for instance, lost or stolen phones could lock users out.
Nevertheless, Meta allows password fallbacks for unsupported devices, according to CNBC TV18. While this fallback option is user-friendly, it undermines the phishing resistance that passkeys aim to provide, as passwords remain a vulnerable point.
Additionally, passkeys are not immune to sophisticated attacks. A 2025 NIST report warns that malware designed to target device authentication could potentially bypass passkeys; however, such attacks are rare, accounting for less than 0.5% of all cyber incidents.
Users must maintain device security to maximize passkey protection, a responsibility Meta's blog post emphasizes but does not fully address.

Is Meta's Ecosystem Ready for Passkey Integration?
Meta's passkey strategy extends beyond logins to Meta Pay and, soon, Messenger, enabling secure payment autofill and encrypted message backups, per Gadgets360. This unified approach, using a single passkey across platforms, streamlines user experience but raises concerns about single-point failures.
A 2025 IDC analysis indicates that systems like Meta's Account Center, which manage passkeys, might attract sophisticated cyberattacks, even though there haven't been any reported breaches yet.
Meta's prior success with passkeys on WhatsApp, rolled out in October 2023 for Android and April 2024 for iOS, provides a blueprint. WhatsApp's passkey adoption reached 30% of its active users by June 2025, per a Statista estimate, indicating Meta's capability to scale this technology.
Still, the absence of passkey support for Instagram, despite its shared Account Center, signals potential delays in full ecosystem coverage, leaving gaps in Meta's security posture.
Passwords Persist as a Weak Link
Despite passkeys' advantages, Meta's decision to retain passwords as a backup option, as noted by Lifehacker, dilutes their security impact. A 2025 Verizon Data Breach Report found that 74% of breaches involved stolen credentials, underscoring the danger of password reliance.
Users accustomed to passwords may resist switching, particularly on desktops where passkeys are not yet supported, per MacRumors. Meta's gradual rollout, starting with mobile devices, risks prolonging this vulnerability window.
Education is critical. Meta's blog post outlines passkey setup via the Account Center, but a 2025 Pew Research survey revealed that 41% of users are unaware of passwordless options, suggesting Meta must invest in awareness campaigns to drive adoption and minimize password use.
Did you know?
In 2019, the FIDO Alliance, which Meta supports, launched its first passkey specification, reducing global password-related breaches by 20% in adopting platforms by 2023, per a FIDO report.
Passkeys Signal a Security Paradigm Shift
The broader industry trend supports Meta's move. Microsoft's default passkey policy for new accounts since May 2025 and Apple's iOS 26 Passwords app enhancements, per The Hacker News, reflect a shift toward passwordless authentication.
Passkeys make it harder for hackers to steal information because they remove the need for passwords, which were involved in 61% of cyberattacks in 2024, according to
Meta's leadership in this trend hinges on its ability to close the password fallback loophole and maintain robust device-level security.
Meta's passkey rollout is a bold step, but its promise of eliminating vulnerabilities remains unfulfilled while passwords coexist. Adoption challenges and ecosystem gaps temper the technology's impact, despite its strength in phishing resistance and user convenience.
What Lies Ahead for Meta's Passkey Strategy?
Meta's passkey rollout marks a pivotal shift toward passwordless authentication, offering robust phishing resistance and streamlined logins for Facebook users. Yet, the persistence of passwords as a fallback, limited desktop support, and slow user adoption pose challenges.
As Meta extends passkeys to Messenger and Meta Pay, its ability to close security gaps and educate users will determine success. Can Meta take the lead in replacing passwords, or will vulnerabilities persist in its hybrid approach?
