How to share recovery codes securely
Recovery codes can bypass ordinary multi-factor authentication, so each unused code should be treated like a powerful single-use password rather than an ordinary note.

Decide whether another person needs a recovery code
Recovery codes commonly bypass a second factor and may provide durable account access. Prefer adding the person through an individual account, delegated administrator role, emergency-access feature, or documented organizational recovery process. Those options preserve attribution and revocation better than a copied recovery set.
If an emergency handoff is unavoidable, send one code rather than the whole set when the service permits it. Do not combine the code with the account name, login URL, username, password, or personal answers. Store the master set offline or in an approved password manager with access controls appropriate to the account.
Verify the requester before preparing a handoff
Account takeover attempts often manufacture urgency. Call a known number, use an existing authenticated workplace channel, or confirm in person. Do not rely on a new email address, display name, incoming phone number, or forwarded thread as proof. For high-impact accounts, require a second approver and record the decision without recording the code.
Agree on a narrow opening window. Create a Strumio link only when the recipient is ready and select one-time retrieval or a short expiration. An optional link password adds a barrier only if it is strong and delivered through a separate channel that is not compromised alongside the link.
Know what one-time encrypted delivery protects
The sender's browser encrypts Strumio content before upload, and the random decryption key remains in the complete URL fragment. This keeps readable recovery codes out of Strumio's stored message record. Atomic one-time consumption can stop a second request from retrieving the encrypted payload after the first valid claim.
That first claim might still belong to the wrong person if the complete URL was forwarded or intercepted. The first viewer can copy, photograph, print, or save the code. Expiration cannot invalidate plaintext already revealed. Protect the complete link, inspect destination addresses, and keep the account provider's revocation tools available.
Handle the code carefully at both endpoints
Use updated devices you control and close unrelated screen-sharing, recording, clipboard-sync, and remote-support tools. The recipient should enter the code directly into the legitimate service after checking the domain. Avoid copying it through shared notes, ticketing systems, documents, or ordinary chat on the way.
After the recipient confirms recovery, remove temporary local copies and delete the delivery message if appropriate. Never ask the recipient to repeat the full code as confirmation. Acknowledging success, code position, or last few non-sensitive characters is usually enough without creating another plaintext copy.
Regenerate and document after recovery
Most services invalidate a used code, but behavior varies. Review the provider's status and generate a fresh recovery set after emergency use, suspected disclosure, staff changes, or loss of a storage device. Revoke unfamiliar sessions, update primary factors, and investigate why normal authentication failed.
Test the recovery plan periodically without circulating live codes. Define owners, approval rules, offline storage, and a replacement process. Strumio can reduce exposure during one focused delivery; it does not replace the account provider's recovery controls, identity verification, monitoring, or incident response.
