How OTP Auto-Paste Works & Is It Safe?

• OTP auto-fill occurs when apps detect a 4-8 digit number in the clipboard or SMS, automatically pasting it into the required field.
• This process relies on pattern recognition technology and temporary clipboard memory.
• Android uses SMS Retriever/User Consent APIs for seamless OTP auto-fill without full SMS access.
• iPhone's System-Level OTP Autofill suggests OTPs from messages directly on the keyboard due to stricter security.
• While generally safe for trusted apps, caution is advised with suspicious apps requesting OTP access.
