When used on the space above any solid top surface, on any side of any flammable block or any side of any obsidian block within a valid unlit Nether portal frame regardless of if there is a solid top surface available, the flint and steel places a fire there.
Flint and steel can be used to light Nether portals, as any fire existing within an appropriate obsidian frame is instantly replaced with Nether portal blocks that occupy the entirety of the frame. Flint and steel cannot light End portals.
Using flint and steel on TNT ignites it. The explosion damage dealt by TNT ignited with flint and steel in this specific way counts as the player's attack. If the player is sneaking, a fire is instead placed on the side of the TNT the flint and steel was used on.
A flint and steel can be used on a creeper or charged creeper to force it to explode. Explosions initiated in this way cannot be cancelled.
When powered, a dispenser containing flint and steel can place fires or ignite relevant blocks such as TNT or campfires in the space directly in front of it. This reduces the flint and steel's durability. A dispenser containing a flint and steel cannot detonate creepers.

Trivia
The name "Flint and Steel" may be misleading as there is a lack of steel in the game and is instead crafted with iron.
In real life, the steel piece is called a fire striker. Before the invention of steel, iron minerals were also used as material for the fire striker, though it was less effective.
In Adventure mode, flint and steel cannot light fires, nor can it ignite nether portals (unless it has the tag CanPlaceOn:obsidian). However, it can still ignite TNT and creepers.
