These layers are related but not interchangeable. The SRP restores a wallet and controls its assets; Farcaster recovery moves your Farcaster ID (fid) between custody addresses after a three-day delay; signer keys authorize messages without being the wallet master key.
Set the recovery address and make a durable offline phrase backup before you lose a phone, replace a wallet, or suspect malware. Neither Farcaster nor a wallet provider can recreate an SRP that has been lost, and anyone who obtains it can control the wallet.

Understand what you are protecting
A Farcaster account is not a single password. The protocol separates a durable Farcaster ID (fid), the custody address that controls ownership of that ID, and signer authorization keys that sign casts and other messages. Your wallet is a separate control system: its Secret Recovery Phrase derives the accounts that hold tokens and other assets.
Farcaster identity (fid)
The fid is the persistent identity recognized by the Farcaster protocol. It can be transferred to a new custody address through the protocol’s delayed recovery process. A transfer changes which address controls the identity; it does not reveal or recreate a wallet’s SRP.

Custody address
The custody address is the account-control layer for the fid. Whoever can authorize activity from that address can manage identity ownership, so protect its credentials and review every transaction before signing. Moving the fid to a different custody wallet is a security-sensitive operation.
Signer keys
Signer keys are delegated authorization keys. They let a client sign messages for the fid without giving that client the custody wallet’s master secret. Remove signers you no longer use and periodically inspect which applications and devices still have authorization.
Wallet and Secret Recovery Phrase
The SRP, also called a seed phrase, is generated when a self-custody wallet is created. It derives the wallet accounts and the assets held by them, and it restores those accounts on another device. MetaMask’s official guidance puts the consequence plainly: “Your SRP is the foundation of your wallet; your password’s importance depends on your setup.” It also says, “Anyone who can access your SRP can control your funds,” and “MetaMask cannot recover your wallet for you.”

A Farcaster recovery address can help you regain identity control, but it cannot replace the SRP for a wallet whose assets are at risk. Conversely, possessing the SRP does not automatically complete Farcaster’s delayed identity-recovery procedure.

Set up Farcaster recovery before an incident
Farcaster’s documented recovery system is intentionally delayed. A designated recovery address can request a transfer of the fid to a new address. The current custody address can cancel that request. If it does not cancel the request within three days, the recovery address can complete the transfer. This delay gives the legitimate owner a window to stop an unauthorized request.
Choose an appropriate recovery address
The protocol documentation allows several designs:
- Another address you control: useful when it is secured independently from the primary custody wallet.
- A trusted multisig: friends or colleagues can share control so one lost device does not become a single point of failure.
- A third-party recovery service: possible where you accept the service’s governance, availability and trust assumptions.
Use an address that will remain accessible if your everyday phone is lost. Do not place the recovery address and the primary custody credentials in the same exposed account or write both secrets in one location.
Configure the address in the client
- Open the official Farcaster client you normally use and enter its account, custody or identity settings. Labels vary by client and version.
- Identify the address currently controlling your fid. Copy the complete address; do not rely on a shortened display such as the first and last few characters.
- Choose Set recovery address (or the equivalent control) and paste or enter the independent address.
- On a separate trusted screen, compare the full destination address character by character. Malware can replace a copied address in the clipboard.
- Approve the transaction or signature and wait for the client to show that the setting is active.
- Record the recovery address and the date you configured it. Keep this record separate from the SRP backup so one discovery does not expose both controls.
Recheck after changing custody
Farcaster’s recovery documentation warns that transferring the fid to a new custody address can unset the recovery address. After any custody-wallet migration, confirm the setting again and re-establish it if necessary. Also check it after a major client update or a recovery event rather than assuming the old configuration followed the fid.

Never enter the phrase into a website, online form, support chat, cloud note, password-reset page, screenshot, or unfamiliar wallet. A person claiming to be support has no legitimate reason to request it. Treat an unsolicited “verification” or “migration” prompt as a likely theft attempt.
Create an offline, durable backup
Write the words in their exact order and preserve capitalization conventions used by the wallet. Paper is easy to create but can be destroyed by water, fire, fading ink or accidental disposal. A steel or fire-resistant mnemonic backup plate is a practical physical option for a durable copy. Choose a reputable seller, inspect the materials and instructions, and assemble it in a private location without photographing the phrase.
Consider two geographically separate physical backups when the balance or identity value justifies it. Each copy increases the number of places that must be protected, so store them in access-controlled locations rather than hiding both in the same room. Do not store a phrase backup beside a note identifying the wallet’s balances or recovery address.
Verify before you put the backup away
- Use the wallet’s built-in verification prompt, if available, to confirm every word and its position.
- Compare the physical copy against the wallet display while offline and undisturbed.
- Check that no word is smudged, abbreviated or substituted with a similar-looking word.
- Seal or secure the backup against casual discovery, and document only its location and creation date in a separate, non-secret record.
What to do if the phrase may be exposed
Assume compromise as soon as the SRP has been typed into an untrusted site, shown to another person, photographed, stored in a cloud service or handled by malware. Do not wait for a transaction to appear and do not ask the person who requested it for help.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
- Use a trusted, malware-free device. If the original computer or phone is suspect, do not use it to create or approve the replacement wallet.
- Generate a completely new wallet and a new SRP. Record the new phrase offline before moving funds.
- Transfer assets from the exposed accounts to the new accounts, checking destination addresses and network fees carefully. If an attacker is actively draining funds, prioritize the most valuable assets and revoke dangerous approvals where the wallet and network support that action.
- Change Farcaster custody to the new wallet through the client’s documented flow. Treat this as an identity migration, not merely a wallet import.
- Set and verify a new recovery address. Remember that a custody transfer may clear the previous recovery setting.
- Review signer keys and connected applications, remove anything unrecognized or unnecessary, and update the device before using it again.
If the phrase is lost but has never been exposed, the wallet provider cannot reconstruct it. Access remains possible only on devices that still contain the wallet or through a correctly preserved backup. Losing the phone is therefore a device-recovery problem; losing both the phone and the SRP backup is a permanent wallet-access risk.
Use another device without copying custody credentials
Copying an EOA seed phrase into a second application expands the number of places where the master secret can be stolen. Farcaster’s Auth Addresses proposal is intended to address this problem by allowing an Ethereum address key type to authenticate on behalf of a Farcaster user. Its goal is secure multi-client access for smart wallets or multiple devices without sharing custody credentials.
Auth Addresses remains proposal-level capability unless the particular client documents support. Do not assume that an app supports it because it displays an “add device” or “connect wallet” button.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Safer choices today
- Prefer a client flow that requests a scoped signature or creates a documented signer key.
- Use the wallet’s official connection and approval screens; read the exact permissions before signing.
- Do not import the custody wallet’s SRP merely to read feeds, draft a cast or test an unfamiliar client.
- After using a temporary device, remove its signer and disconnect applications you no longer need.
An app-created wallet can be convenient. Farcaster’s permissionless-onboarding discussion also recognizes seed-phrase loss as a user risk and describes mobile key-manager backup as a way to reduce loss. Treat an app backup as an additional recovery route only when its documentation explains how it is protected; it is not permission to disclose the phrase to a person or untrusted service.

Harden the devices that display or sign
Offline phrase storage protects the master secret, while device security protects the keys and approvals used during normal operation. You need both.
- Lock the device: use a long passcode and enable biometrics backed by that passcode. Avoid a short, reused PIN.
- Update promptly: keep the operating system, browser, wallet and Farcaster client current, installing them from official stores or verified publishers.
- Use malware protection: computers used for signing or phrase handling should have reputable endpoint protection and should not run pirated software or unknown browser extensions.
- Reduce data leakage: disable screenshots, clipboard synchronization and automatic cloud backups for phrase material where the operating system permits.
- Check the publisher and domain: phishing applications often copy names and icons. Verify the developer, domain and download source before installing.
- Inspect every approval: confirm the network, destination, amount, permissions and contract before signing. A familiar-looking Farcaster prompt can still contain a malicious transaction.
These controls do not make an online phrase safe. The SRP should remain offline; the device should access it only when the wallet’s legitimate recovery process requires it.
Choose a storage and custody approach
No method eliminates every failure mode. Compare options by durability, privacy, verification and independence rather than by appearance or price.
Recommended Free Tools
| Method | Strength | Weakness or failure mode | Best practice |
|---|---|---|---|
| Paper backup | Simple, inexpensive and fully offline | Vulnerable to fire, water, fading and accidental discovery | Use archival materials, a private location and a second protected copy when appropriate |
| Steel or fire-resistant plate | More resistant to common fire and water damage; durable for long-term storage | Still vulnerable to theft or someone reading the completed plate; assembly errors are possible | Buy from a reputable marketplace, verify the word order and keep it access-controlled |
| Cloud note, photo or password-manager entry | Convenient remote access | Creates an internet-accessible copy that can be breached, synced or shared accidentally | Do not use for an SRP |
| App-managed backup | May reduce loss risk during ordinary phone replacement | Protection depends on the app’s design, account security and recovery process | Use only documented, reputable mechanisms and retain an independent offline backup |
| Hardware wallet or isolated signer | Can keep signing keys away from a general-purpose phone or computer | Requires careful setup, compatibility checks and a separate recovery plan | Confirm Farcaster and network support before purchase; protect its recovery material offline |
| Multisig recovery address | Removes one person or device as the sole recovery point | Coordination, member loss and governance failures can delay recovery | Choose reliable participants, document the procedure and test it before an emergency |
For a custody method, evaluate recovery independence, multi-device support, signer isolation, clarity of transaction confirmation and the consequences of losing the primary device. For phrase storage, ask whether the method survives fire and water, resists casual discovery, lets you verify word order, supports a second backup and ever exposes the phrase to an internet-connected device.
Recovery playbook for a lost phone or wallet
If the phone is lost but the SRP is safe
- Install the wallet and Farcaster client only from official sources on a trusted replacement device.
- Restore the wallet using the offline SRP, never by sending it to a helper or typing it into a web page.
- Check balances and transaction history, then rotate signers and remove the lost device’s authorizations where the client supports it.
- Confirm the custody address and recovery address before posting or approving transactions.
If the custody device is unavailable
Use the preconfigured recovery address to request a transfer to a new custody address. Monitor the three-day cancellation window from a trusted device. If the original custody address is still secure, cancel any request you did not initiate. After the delay expires, complete the transfer and immediately establish a new recovery address.
If the wallet itself is compromised
Prioritize moving assets to a newly generated wallet, then migrate Farcaster custody and review signers. Do not confuse a successful fid transfer with recovery of funds: tokens remain controlled by the wallet accounts derived from the SRP until you move them.
Routine maintenance checklist
- Confirm the active custody address and recovery address at least after every custody-wallet change.
- Check that your physical SRP backup is readable and has not been damaged.
- Review connected applications and signer keys; remove stale or unknown entries.
- Install operating-system and client updates from verified sources.
- Verify that trusted recovery participants still have access and understand the procedure.
- Record dates and public addresses, but never record the SRP in the same log.
Farcaster’s protocol documentation describes the three-day recovery delay; MetaMask’s official guidance describes the SRP as the wallet’s foundation and states that the provider cannot recover it. Those are different guarantees: one gives an identity owner time to cancel a transfer, while the other makes offline phrase custody the user’s responsibility.
