What is 1office?

We flagged 1office.co as phishing. The page behavior matches a common credential-theft flow: impersonation first, urgency second, data request last.

Typical prompts on sites like this include account alerts, failed-delivery notices, or "verify now" dialogs asking for passwords, card numbers, or one-time codes. Do not submit credentials here. Open the real service in a new tab and check your account directly.
