önkitölt

Önkitölt is a term used in Hungarian computing to describe the automatic filling of form fields with data previously provided by the user. It is commonly implemented in web browsers, mobile platforms, and password management tools, and is designed to speed up recurring data entry in online forms. The feature distinguishes between autofill and autocomplete: autofill refers to the automatic insertion of stored data into form fields, whereas autocomplete commonly denotes the browser’s mechanism for offering suggestions based on past input.

In practice, autofill works by storing user information such as names, addresses, email addresses, phone numbers, and, in some cases, payment or credential data in a secure local vault or cloud-synced profile. When a user encounters a compatible form, the platform can fill or suggest values for corresponding fields, often requiring user confirmation or a single action to apply. Websites can opt out by setting autocomplete attributes that disable autofill.

Security and privacy considerations are central to önkitölt. Stored data can be sensitive; improper access or malware can expose it. Modern implementations use encryption, access controls, and user prompts; more advanced solutions rely on password managers with master authentication and, optionally, cloud synchronization. Users should be aware of phishing risks where attackers mimic forms, and consider configuring autofill to limit stored data or disable it on untrusted sites.
