Attention users! WhatsApp may block logins on phones with outdated software: Report

WhatsApp is reportedly testing a new security measure that could prevent some users from logging into the messaging app if their phones are running outdated versions of Android or iOS.

According to WhatsApp feature tracker WABetaInfo, selected users are seeing a new warning when they try to access their accounts. The prompt asks them to update their phone's operating system before they can continue using WhatsApp.

The change is reportedly being delivered through WhatsApp's servers, meaning users do not need to install a separate WhatsApp update to receive the warning. It is currently being rolled out to a limited number of accounts on both Android and iOS.

Users who receive the warning are directed to their device settings to check for an available software update. WABetaInfo reports that the prompt does not provide an option to bypass the requirement and continue using WhatsApp.

However, WhatsApp has not publicly specified which Android or iOS versions are affected by this particular login check, nor has it announced a wider rollout.

Why is WhatsApp asking users to update their phones?

The reported move appears to be aimed at ensuring WhatsApp runs on devices with more up-to-date security protections.

Older operating systems may no longer receive security fixes and can lack features required by newer versions of apps. WhatsApp itself says it regularly reviews the operating systems it supports and retires older versions to keep pace with technology and security requirements.

WhatsApp's official support information currently lists Android 6.0 and newer as supported. On iPhone, iOS 15.1 and newer are currently supported, although WhatsApp says that from November 30, 2026, only iOS 15.5 and newer will be supported.

The company has also already ended support for Android 5.0 and 5.1, with the change taking effect on September 8, 2026.

Will WhatsApp stop working on every old phone?

Not based on the information currently available. The newly reported login restriction is being tested with selected accounts, and WhatsApp has not said that every device running an older operating system will immediately face the same block.

It is also important to distinguish this reported login check from WhatsApp's normal policy of ending support for an operating system.

When WhatsApp retires an unsupported operating system, the company says users are notified in advance and reminded to upgrade so they can continue using the service.

WhatsApp also tests warnings for unofficial web clients

WABetaInfo has also reported a warning being tested for users who connect their accounts through unofficial WhatsApp Web clients. The warning appears in the Linked Devices section and asks affected users to switch to the official WhatsApp Web client.

WhatsApp has also been testing other privacy and security features, including Restricted Chats.

For now, however, the outdated-software login requirement remains a limited reported rollout rather than a confirmed WhatsApp-wide change. Users who see the warning will need to update their phone's operating system, if an update is available, before they can continue logging in.
