Two-factor authentication has become the minimum standard for protecting online accounts, and for good reason – passwords alone are not enough. But once you enable 2FA across dozens of services, a practical question emerges: where should you store and generate those TOTP codes? The answer that an increasing number of security-conscious users are arriving at is their password manager.
This is not a fringe position. Password managers with built-in TOTP support offer a workflow that is more secure in practice than the alternatives, because they solve the problems that cause real-world 2FA failures: lost phones, unrecoverable codes, and the friction that leads people to avoid enabling 2FA in the first place.
How TOTP Works (Brief Refresher)
Time-based One-Time Passwords are generated from a shared secret – a string of characters that both your authenticator and the service agree on during setup. The authenticator combines this secret with the current time to produce a six-digit code that changes every 30 seconds. The service performs the same calculation on its end, and if the codes match, you are in.
The critical detail is that the shared secret is the real credential. The six-digit codes are ephemeral. If you have the secret, you can generate codes on any device, with any compatible app. If you lose the secret, you lose access.
The Case for Consolidation
One App, One Workflow
With a standalone authenticator app, logging into a service requires switching between two applications: your password manager to retrieve the password, and your authenticator to retrieve the code. Some people use a third app for their email-based verifications. This juggling act is not just inconvenient – it is an attack surface. Phishing sites exploit the time pressure of typing a TOTP code before it expires, knowing that users are frantically switching between apps.
When your password manager holds both the password and the TOTP secret, the login flow becomes a single action. Password managers like PanicVault can autofill both the password and the TOTP code in one step, giving phishing sites less opportunity to exploit the gap between entering credentials and entering a code.
Encrypted, Synchronized Backup
This is the single most important advantage, and it is not discussed enough. Standalone authenticator apps like Google Authenticator historically stored TOTP secrets only on the local device with no backup mechanism. If you lost your phone, broke the screen, or factory-reset without thinking, every 2FA secret was gone. You would spend hours or days going through account recovery processes, proving your identity to support teams, and in some cases permanently losing access to accounts.
A password manager stores TOTP secrets in the same encrypted database as your passwords. That database is backed up, version-controlled, and synchronized across your devices using whatever method you choose – cloud sync, local file transfer, or both. If your phone falls into a lake, you open your vault on another device and every code is waiting for you.
The importance of reliable TOTP backup strategies cannot be overstated. More people are locked out of accounts by losing their authenticator than by any attack that 2FA was designed to prevent.
Autofill Eliminates Phishing Risk
When your password manager autofills both the password and the TOTP code, it checks the URL of the site you are visiting against the URL stored in the vault entry. If you are on g00gle.com instead of google.com, the password manager will not offer to fill anything. This domain-matching behavior is a powerful anti-phishing defense that standalone authenticator apps cannot provide, because they have no awareness of which site you are visiting.
PanicVault, built on the KeePass ecosystem, stores TOTP secrets directly in the encrypted KDBX database alongside the associated credentials. When you visit a site, PanicVault matches the URL, fills the password, and copies the current TOTP code – all in one action, all with domain verification.
Cross-Device Availability
Standalone authenticator apps typically live on a single phone. If you are at your desk and need a code, you reach for your phone. If your phone is charging in another room, you walk to get it. If you are traveling and your phone’s battery dies, you wait.
When TOTP secrets live in your password manager, they are available everywhere your vault is available – your phone, your tablet, your laptop, your desktop. Any device that can open your vault can generate the code. This is particularly valuable for users in the KeePass ecosystem, where the database file can be stored and accessed using any compatible application across any platform.
Addressing the Single Point of Failure Concern
The most common objection to consolidating TOTP into your password manager is the “single point of failure” argument: if someone compromises your vault, they get both your passwords and your 2FA codes.
This concern deserves serious analysis rather than dismissal, but it is less compelling than it appears.
The Threat Model Reality
For the vast majority of users, the realistic threats to their accounts are:
- Credential stuffing – Automated attacks using passwords from data breaches. 2FA of any kind blocks these entirely, regardless of where the TOTP secret is stored.
- Phishing – Tricking you into entering your password on a fake site. Password manager autofill blocks this. Standalone authenticator apps do not.
- SIM swapping – Redirecting SMS-based 2FA to the attacker’s phone. TOTP is immune to this regardless of where it is stored.
- Device theft – Someone steals your phone. If your vault is locked (and it should auto-lock), the attacker has neither your passwords nor your TOTP codes. If you use a standalone authenticator with no device lock, the attacker has your TOTP codes immediately.
- Vault compromise – An attacker obtains your master passphrase and your vault file. Yes, they get everything. But this attack is equally devastating even without TOTP in your vault, because they already have all your passwords.
The “single point of failure” scenario requires the attacker to compromise your vault’s master passphrase, which is exactly the attack that your vault’s encryption and key derivation are designed to prevent. If your vault is compromised, the TOTP codes being elsewhere does not save your accounts – the attacker already has every password.
When Separation Actually Matters
There is one scenario where separation provides meaningful additional security: if an attacker compromises your vault but you discover the breach before they use the stolen credentials. In that narrow window, having TOTP codes in a separate app buys you time. The codes in the vault are useless without the corresponding TOTP secrets.
This is a real but narrow benefit. For users who manage high-value targets (cryptocurrency exchanges, corporate admin accounts), using a separate hardware security key for those specific accounts is a more robust solution than splitting TOTP across apps.
For the other 95% of accounts, the practical security gained from consolidated backup, autofill-based phishing protection, and universal availability far outweighs the theoretical risk of vault compromise.
Comparing to Standalone Authenticator Apps
Google Authenticator
Google Authenticator has improved significantly since its early days. It now offers cloud backup and cross-device sync, which addresses the historic problem of losing codes when you lose your phone. However, it remains a separate app in a separate workflow, it provides no phishing protection through URL matching, and your TOTP secrets are stored on Google’s servers rather than in an encrypted database under your control.
Authy
Authy was one of the first authenticator apps to offer cloud backup and multi-device sync. It encrypts your TOTP secrets with a backup password. The trade-off is that Authy is a proprietary service – if the company discontinues the product or changes its terms, your migration path is unclear. Exporting secrets from Authy is notoriously difficult by design.
Microsoft Authenticator
Microsoft Authenticator offers cloud backup through a Microsoft account. Like Google Authenticator, it requires a separate app and workflow, does not match URLs for phishing protection, and ties your 2FA secrets to a specific vendor’s ecosystem.
The Password Manager Advantage
When you compare the best authenticator apps against a password manager with TOTP support, the password manager wins on every practical dimension except one: the theoretical risk of consolidation. It provides encrypted local backup, URL-based phishing protection, cross-device sync without vendor lock-in, and a single streamlined workflow. For users who want to move their codes to a password manager, the migration process is straightforward and the benefits are immediate.
Practical Implementation
Setting Up TOTP in Your Password Manager
Most services that support 2FA will show you a QR code during setup. That QR code encodes a URI containing the TOTP secret. Instead of scanning it with a standalone authenticator, you scan it with your password manager or paste the secret directly into the TOTP field of the relevant vault entry.
In PanicVault, adding a TOTP secret is part of the standard entry editing workflow. The secret is stored as a protected field in the KDBX database, encrypted with the same multi-layered encryption that protects your passwords.
Migration from a Standalone App
If you already have dozens of TOTP codes in Google Authenticator or another standalone app, the migration process involves re-enrolling 2FA on each service. Visit each service’s security settings, disable 2FA, re-enable it, and this time scan the QR code with your password manager instead. This is tedious but is a one-time process, and it is an opportunity to verify that you have backup codes stored securely for every account.
Maintaining a Backup
Even with TOTP in your password manager, you should maintain backup access to your accounts. Store your recovery codes in your vault alongside the TOTP secrets. Keep an encrypted backup of your vault in a separate location. The goal is to ensure that no single hardware failure or loss can lock you out of your digital life.
The Bottom Line
The debate over where to store TOTP codes often focuses on theoretical attack scenarios while ignoring the overwhelmingly more common failure mode: losing access to your own accounts because your authenticator app was on a device you no longer have.
A password manager with TOTP support eliminates that failure mode while adding phishing protection, streamlining your login workflow, and keeping your 2FA secrets encrypted under your control. For the vast majority of users, this is the most secure and practical approach to two-factor authentication – not because consolidation has zero trade-offs, but because the practical benefits decisively outweigh the theoretical risks.
The password management landscape has evolved to the point where the best managers are also the best authenticators. Using them as both is not a compromise – it is an upgrade.
