Why it matters more than a password
A seed phrase restores your entire wallet on any device. Anyone who has it owns your funds outright — there is no reset, no support line, no reversal.
Where people go wrong
Screenshots, cloud notes, password managers synced online, and typing it into a website are the most common leaks. Any phrase that ever touches an internet-connected text field is at risk.
Safer practice
Write it on paper or steel, store copies in separate physical locations, and never type it into any website or app except your wallet during setup or restore. No legitimate site or support agent will ever ask for it.
