WhatsApp has rolled out a server-side update that prevents users from logging in if their device runs an outdated version of iOS or Android. The change, which does not require a new app version, displays a screen prompting users to update their operating system before accessing their accounts. The message explains how to check the current OS version and directs users to their device’s Settings to apply a system update.
WhatsApp states this measure is for security reasons, aiming to protect users from known vulnerabilities in older OS versions that could be exploited to install malware. The company has not specified which exact iOS or Android versions are affected, but the update is rolling out to both platforms. Users who see the login block screen must update their phone’s OS to regain access to WhatsApp.
This move underscores WhatsApp’s effort to mitigate risks associated with outdated software, even as the app maintains end-to-end encryption. The feature is active now, though no official announcement has detailed the targeted version thresholds.
