Auto-Populate vs. Autopopulate vs. Auto Populate
“Auto-populate” is a dictionary headword for automatically filling fields or data, and “autopopulate” is also documented as an alternative form. The open form “auto populate” may appear when writers separate the prefix in informal or product-specific text, but it is not the reviewed dictionary headword.
Use “auto-populate” as the safest edited spelling; “autopopulate” is also documented. Treat open “auto populate” as a house-style or product wording choice rather than the default lexical spelling.

Quick tests
Lexical-form test
Are you writing ordinary edited prose without a product-specific spelling rule?
If yes: Use “auto-populate.”
If no: If a product or house style deliberately uses “autopopulate” or an open UI label, follow that controlled wording.
Caveat: Do not turn a dictionary-headword preference into a claim that every open-form interface label is impossible.
Examples
The form can auto-populate the city field.
The hyphenated form is the conservative edited choice.
The application can autopopulate saved values.
The closed form is documented as an alternative.
Match a product’s exact UI wording when quoting the interface.
UI wording can be house-specific.

Editing Choice
For general edited prose, “auto-populate” is the clearest conservative choice unless a product or house style specifies otherwise.
Open Form Boundary
Do not label every open “auto populate” occurrence impossible; interfaces and house styles can separate words, but that is not the reviewed lexical headword.
