Google is testing a restrictive storage policy for newly created Gmail accounts. According to recent user reports on social media and tech publications, some new Gmail accounts are now default-limited to 5GB of free storage, down from the traditional 15GB.
To unlock the standard 15GB threshold, users are required to link and verify a phone number with their account. This testing phase was first spotted by users and subsequently reported by Android Authority, raising questions about Google's underlying motives.
In response to these reports, Google issued an official statement confirming the test. "We are testing a new storage policy for newly created accounts in select regions. This will help us continue to provide high-quality storage services while encouraging users to improve their account security and recovery options," the company stated.
[AgentUpdate Depth Analysis] On the surface, Google’s strategy is about user security, but underneath, it represents a critical escalation in the defense against automated botnets and AI Agents. In the emerging AI Agent ecosystem, email addresses serve as the primary gateway for agents to perform cross-platform authentications and automated tasks. By restricting unverified accounts to 5GB and demanding phone verification, Google raises the operational and financial barrier for deploying malicious Sybil multi-agent systems. While traditional CAPTCHAs are increasingly bypassed by advanced multimodal LLMs, linking digital accounts to physical-world identity markers (like phone numbers) is becoming the new standard for bot mitigation. This shift will likely accelerate the adoption of decentralized identity (DID) frameworks within the AI Agent community.
