It is your key, not your password
A password can be reset by a company. These words cannot. They create your keys right on your phone. Blitz never sees them.
What are 12 words?
When you make a Blitz wallet, you get 12 ordinary words. Those words help restore your wallet. Here is what the words mean and how to protect them.
Plain English
What is a seed phrase?
A seed phrase is a set of words that creates your wallet. Blitz uses 12 words. In a compatible app, they can restore the corresponding wallet on another device.
Your money is not on your phone
Your Bitcoin lives in the network. Your phone just holds the key. Lose the phone and the money still sits there, waiting for your words.
Same words, same wallet
Type the same 12 words in order on any phone and the same wallet opens. That is how recovery works. It is also why sharing them gives everything away.
Never share your 12 words
Blitz support will not ask you to send them by email, chat, or form. Official wallet restore and recovery tools may ask you to enter them. Verify the destination before entering a phrase.
Do this once
Back up your words in 5 steps
Do it the day you create your wallet. It takes five minutes.
Write them on paper
Copy all 12 words by hand in exact order. Number them 1 to 12. Use pen and paper. No screenshots. No typing into notes apps.
Check every word twice
Read the paper back against the screen. A wrong word can prevent the wallet keys from being restored. Fix mistakes now while the screen is still open.
Store the paper offline
Keep it somewhere dry and protected, such as a locked drawer or safe. Avoid photos, email, and cloud drives because digital copies can be exposed if an account or device is compromised.
Keep a protected backup
If you lose the phrase and can no longer access the wallet on a device, you may be unable to restore the wallet keys. Blitz cannot recreate the phrase. Recovery of Spark funds also depends on the supported recovery path and operator availability.
Right and wrong

| Notes app, email, or cloud drive | Never | A compromised account can expose a digital copy of the phrase. |
| Typing words into any website | Never | Enter the phrase only in a verified restore or recovery flow you intend to use. |
