🔥 April 2026 Update: Anthropic's Rapid Iteration & Identity Verification Policy
Since the launch of Claude Cowork in early 2026, Anthropic has maintained a near daily update cadence. According to multiple tech media reports, Claude Opus 4.7 is expected to launch this week — marking another capability leap beyond Claude 4.5/4.6.
At the same time, Anthropic updated its Help Center on April 15, 2026 with a policy that has drawn significant controversy: the platform is introducing identity verification for "certain use cases" — triggered when users access specific capabilities, during routine integrity checks, or to meet safety and compliance requirements. Many users speculate this may be a precursor to real-name verification targeting users in certain regions.
Anthropic's official statement is direct: "Being responsible with powerful technology starts with knowing who is using it. Identity verification helps us prevent abuse, enforce our usage policies, and comply with legal obligations."
Key verification requirements (from official docs):
- A valid, physical government-issued photo ID (passport, driver's license, national ID card, etc.); photocopies, digital IDs, and temporary paper IDs are not accepted
- A device with a camera for a live selfie; the process typically takes under 5 minutes
- Anthropic works with third-party identity provider Persona Identities; your ID and selfie are held by Persona, not stored on Anthropic's systems, encrypted in transit and at rest, and not used for model training
Impact on SMS-verified accounts
This policy raises questions about continued access to Claude:
- Even users who registered with help from SMS platforms like SMS-Act may encounter identity verification at a later stage
- Existing account holders may also be prompted to verify when accessing certain capabilities
- Once fully rolled out, accounts that cannot complete identity verification may lose access
Recommendation: Register your Claude 4.5/4.6 account now via SMS-Act, enable 2FA and a recovery email, and prepare a physical government-issued ID in advance for future identity verification. Keep an eye on official Anthropic policy updates.
