July 30, 2026 · 5 min read · 0 views
You can set up and manage multiple TOTP accounts on Authy by creating separate Authy profiles for each virtual phone number, allowing secure and flexible two-factor authentication with ease.

Overview of Authy and Virtual Phone Numbers

Authy is a popular two-factor authentication (2FA) app that generates Time-based One-Time Passwords (TOTP) to secure user accounts across a wide range of online services. Unlike traditional SMS-based 2FA, Authy can also deliver codes via the app, increasing security and convenience.

Virtual phone numbers are software-based numbers not tied to physical SIM cards. They can receive SMS messages and voice calls, making them ideal for receiving verification codes or managing multiple phone identities without multiple devices or SIMs.

Important context.

Authy links each user account to a single phone number, which is used for initial verification and recovery. Using virtual phone numbers allows the creation of multiple independent Authy accounts for managing separate 2FA tokens.

Setting Up Multiple Authy Accounts with Virtual Numbers

To manage multiple TOTP accounts using Authy with virtual phone numbers, you must create individual Authy accounts for each virtual number. Here is the step-by-step process:

  • Step 1 — Acquire virtual phone numbers Use a reliable provider such as SMSVerifier to buy virtual numbers from your preferred countries.
  • Step 2 — Register a new Authy account Download the Authy app or use the desktop client, then sign up using one virtual phone number per account.
  • Step 3 — Verify the virtual number Receive the SMS or voice call verification code on your virtual number dashboard and enter it into Authy.
  • Step 4 — Add TOTP tokens Scan each service’s QR code or enter the secret key to add TOTP accounts under this Authy profile.
Pro tip.

Use separate browsers or device profiles to keep multiple Authy accounts logged in simultaneously if you use desktop clients or browser extensions.

One Authy account per phone number is the fundamental design — virtual numbers let you scale by creating multiple independent accounts.

Managing Multiple TOTP Accounts Inside Authy

Once you have multiple Authy accounts set up for various virtual phone numbers, managing your TOTP tokens becomes organized and centralized within each account.

Authy supports multiple TOTP tokens per account, allowing you to handle many services like Google, Facebook, Instagram, and more. Each token appears as a separate entry with its own rotating code.

Pro tip.

Label each TOTP token clearly inside Authy to avoid confusion when switching between multiple accounts.

For users managing many Authy accounts, consider these approaches:

  • Use separate devices or virtual machines for each Authy account to avoid session conflicts.
  • Enable Authy multi-device sync cautiously if you want to access tokens across devices.
  • Backup your Authy accounts to secure cloud storage to prevent token loss.

Security Best Practices for Virtual Number 2FA

Using virtual phone numbers with Authy can increase your 2FA scalability but comes with security considerations.

Common pitfall.

Avoid using untrusted virtual number providers; compromised or recycled numbers can lead to account takeover risks.

  • Choose reputable virtual number providers with good track records, like SMSVerifier, which supports over 4,000 services and offers prompt SMS delivery.
  • Protect your Authy app with a strong password and enable biometric locks where possible.
  • Regularly audit your virtual numbers and retire any unused ones to reduce attack surface.
  • Consider combining Authy with hardware security keys for high-value accounts.
Important context.

Virtual numbers are less susceptible to SIM swapping than physical SIM cards but require strict access control to prevent unauthorized use.

While using Authy with virtual phone numbers, you might encounter some challenges. Here are frequent problems and their fixes:
