Yes, in limited cases. A secure written backup can be safer than repeated password reuse when users cannot reliably manage digital tools. The key is to treat it as a controlled exception, store it in a physically secure place, and keep the broader priority on reducing account sharing, reuse, and credential stuffing exposure.
Why low-tech password backups can be the safer exception
Low-tech backups are not a replacement for good password practice, but they can be a pragmatic exception when a user cannot reliably use a password manager. The security question is whether the backup reduces risky workarounds, such as reused passwords, shared accounts, or predictable resets, without creating a wider exposure than the problem it solves.
A controlled written backup is only defensible when it is genuinely limited in scope. The backup should be for a small set of critical accounts, not a general habit, and it should sit inside a process that still encourages unique passwords and avoids duplicate use across services.

The key trade-off is operational, not just technical. If a user is likely to forget, lock themselves out, or repeatedly reuse a weak password because the approved digital tool is too hard to use, a physical fallback can lower real-world exposure. The backup becomes part of access resilience, not a license to weaken the rest of the account estate.
How to keep a written backup from becoming a new credential risk
A paper backup only helps when the storage and handling controls are tighter than the risks it is replacing. That means protecting it from casual viewing, limiting who knows it exists, and preventing it from turning into a shared family note, desk drawer list, or photo on a phone.
One practical rule is that the backup should hold the minimum necessary information to restore access, not a broad inventory of accounts and secrets. If the note also becomes a map of high-value services, recovery questions, or other authentication material, it has crossed from convenience into concentration risk. Breach history shows how quickly stored secrets and backup material can be abused when attackers reach an adjacent trusted environment. LastPass breach 2022
For organisations, the governing principle is that a paper backup should never be the default control for the whole workforce. It is better treated as an exception for a defined group, with ownership, storage rules, recovery steps, and periodic review. That prevents a temporary accommodation from becoming an unmanaged long-term dependency.
What good practice looks like for teams supporting difficult users
Support teams should first ask whether the user problem is accessibility, training, device compatibility, or account design. Many apparent password manager failures are really onboarding failures, and the better fix is simpler password flows, better recovery support, or a different approved tool rather than abandoning digital credential management altogether.
When a low-tech backup is approved, the decision should be explicit and documented. Good practice is to define who can approve the exception, which accounts it covers, where the backup is stored, and how it will be replaced if the user’s situation changes. That keeps the exception bounded and makes review possible instead of informal and permanent.
At scale, the important signal is whether the exception pool is shrinking. If the number of users relying on paper backups keeps growing, the issue is probably structural: poor usability, inaccessible tooling, or weak recovery design. That is the point where the organisation should improve the credential experience rather than normalise physical workarounds.
Risk and Threat Considerations
Written password backups reduce one class of failure, but they introduce physical disclosure risk, especially if they are copied, photographed, misplaced, or stored with other sensitive notes. The control becomes dangerous when people assume paper is automatically low risk and stop managing it like a credential.
Failure mechanism: The backup is discovered by an insider, visitor, cleaner, family member, or intruder, or it is captured in a photo, scan, or note sync and then reused to access accounts. The same problem appears when the backup becomes the easiest source of shared credentials in a workplace.
Impact: The organisation can lose confidentiality and account integrity at the exact point where the backup was supposed to reduce friction. In practice, that can mean account takeover, unauthorised reuse across services, and a larger blast radius than a single forgotten password would have caused.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5 and CIS Controls v8 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Covers secure handling and lifecycle of passwords and fallback authenticators. |
| IA-2 — Identification and Authentication (Organizational Users) | Applies to user authentication design when password manager difficulty affects access methods. | |
| Recommendation — Control backup credential handling, storage, and rotation under IA-5. Ensure user authentication remains reliable when approved fallback methods are used. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Supports governed exceptions and controlled access to accounts when backup methods are used. |
| Recommendation — Define and enforce access rules for any approved password backup process. | ||
| CIS Controls v8 | CIS-5 — Account Management | Relevant to reducing shared passwords, reuse, and unmanaged access paths. |
| Recommendation — Manage accounts to minimise password sharing and exception drift. | ||
Practitioner Guidance
What to prioritise: Treat the backup as an exception control for a specific user need, not as a parallel password strategy. If the user can be supported with a simpler approved digital method, that is usually the better long-term control.
What to verify: Confirm that the backup is stored in a physically secure place, covers only the accounts it must cover, and is not duplicated in photos, shared notes, or email. Also verify that the user understands it is not for day-to-day use.
Common mistake: Organizations often approve a low-tech fallback without defining ownership, review, or replacement criteria. That turns a temporary accommodation into unmanaged credential sprawl.
Practitioner takeaway: Use paper or other low-tech backups only when they clearly reduce real user workarounds, and keep them narrow, physically controlled, and subject to review so convenience does not become credential exposure.
