Security Considerations

While grammarly.io is an established platform, these capabilities require extra vigilance.

File Hosting

grammarly.io allows users to upload and share files. Any file you download was uploaded by another user—not the platform operator. Scan downloads with antivirus software and only download from sources you trust.

Identity Provider

grammarly.io provides "Sign in with..." authentication for third-party websites. Attackers create fake login pages that look identical to the real one. Always check the URL bar shows the exact correct domain before entering your password.

Document Hosting

grammarly.io hosts documents and pages shared via links. Because the domain is trusted, links pass through email spam filters easily. Attackers exploit this to host fake invoices, login pages, or malware download prompts.

User-Generated Content

grammarly.io hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

Remember: The platform itself is established, but even established platforms can be abused.
