Wallet Backup
Your own encrypted copy of your wallet, and how to keep it safe.
Fiber doesn't hand you a seed phrase to write down. Instead, you can export an encrypted backup of your wallet seed whenever you like. With the backup file and its password, Fiber's recovery tools get your private balance and your private keys out on your own device, without the Fiber app.
What the backup is
- A file: a
.fiberseedfile named likefiber-wallet-backup-2026-10-28.fiberseed. - What's in it: your wallet seed, encrypted with a password you choose. Opening the file shows encrypted data, not words. That's expected, because Fiber wallets don't use a 12- or 24-word recovery phrase, and none exists to show.
- One per account: each Fiber account has its own wallet and its own backup.
- How sensitive it is: anyone with the file and its password can take every asset in your wallet. Store them separately, and never share either one, including with Fiber support.
Export your backup
On mobile, go to Settings > Security > Export wallet seed. On the web, go to Settings > Backup & export.
On mobile, read the backup explanation and tap Continue to set the file password. The Recovery tools link opens the recovery guide.
- Choose a File password of at least 12 characters, and enter it again to confirm. This is a new password for this file only. It is not your Fiber sign-in, and it never leaves your device.
- Tick the box confirming you understand you are responsible for the file and password, then tap Download encrypted seed.
- Confirm it's you. With extra protection off, choose a code sent to your verified email. If you have none, use your Fiber account password. That password option is only available when you have no verified contact; it is separate from the file password you just chose. With extra protection on, use a passkey, an authenticator code, or a backup code. If App Lock is on, Fiber asks for Face ID or your passcode too.
- Save the file. On mobile, the share sheet opens. Save the file to Files, a drive, or another safe place. If you close the sheet without saving, nothing is kept, so export again. On the web, your browser downloads the file.
On older mobile builds, encrypting the backup can take longer. If you see Encrypting your backup on this device… with a percentage, keep Fiber open until the share sheet appears.
Each export triggers a "Wallet seed exported" alert by push and email.
Your file password
- Fiber never sees the file password, and can't reset or recover it.
- Each export has its own password. Two files made on the same day get the same name, so label them if you keep more than one.
- If you forget a file's password, that file can't be opened. While you can still sign in, export a new backup with a new password and delete the old file.
- Type the password exactly, including capital letters and spaces.
Use your backup
Fiber's Recovery Tools open your backup on your own device. Neither tool sends your file, password, or keys anywhere.
- Fiber Recovery: a page at recovery.fiber.so that finds your private balance, sends it to any address, and recovers private keys. Start here.
- Fiber CLI: prints private keys for EVM networks and Solana, and lists your private balances.
Your private balance, which is where most of your USD sits, won't appear in MetaMask or another wallet, even after you import a recovered private key. Fiber Recovery finds it and sends it out.
Don't import the .fiberseed file itself into MetaMask or another wallet. It isn't a wallet keystore, so wallets reject it, for example with "not a V3 wallet." Get the private key from a recovery tool instead.
If you didn't export it
If you get a "Wallet seed exported" alert you don't recognize:
- Open Settings > Security > Logged in devices and revoke the device named in the alert.
- Contact support right away: ask the assistant for a person, or open a ticket from Settings > Support. See Support tickets.
Troubleshooting
| What you see | What it means | What to do |
|---|---|---|
| Android freezes after the security code | Older app versions could freeze while encrypting the backup | Update Fiber and try again, or export from the web app |
| Saving files is not available on this device | The phone can't save the file | Export from the web app instead |
| Wallet export requires an updated native build with protected keys | Your app version is too old | Update the Fiber app |
| The wallet seed could not be exported. Try again. | The export didn't finish | Try again, or use the web app |
| A recovery tool says the password is wrong | The password doesn't match this file | Type it exactly. Each export has its own password. If you can't recover it, export a new backup. |
