A single mobile app icon for a password manager, shown alone and centered on a plain light background with a soft, subtle shadow. Use a standard iOS and Android rounded-square shape with a full-bleed background in the Primary Color. Place the Central Symbol in the center, filling roughly 60 to 70 percent of the icon with even padding. Render it as a bold, simple flat shape in the Secondary Color, with a confident silhouette that remains instantly recognizable at 48 pixels. If the Central Symbol is a letter, show only that one letter. Use flat color with clean edges, no gradients, no texture, no glossy effects, no inner border, and no extra objects. Keep the design to the Primary Color, Secondary Color, white, and at most one additional supporting color. Do not add text, labels, logos, watermarks, or surrounding interface elements.
Use these details:
Central Symbol: "simple padlock silhouette"
Primary Color: "dark slate"
Secondary Color: "warm white"
