The short version

  • Only Authy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Authy there is no export function for stored TOTP secrets, so moving to a different authenticator means disabling and re-enrolling two-factor authentication on every account individually, which is the reason most users stay rather than a reason anyone should choose it.; Bitdefender VPN the network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.
  • They diverge on capability: Authy covers Encrypted cloud backup, Bitdefender VPN covers Suite integration.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Authy

  • Households wanting one security subscription covering malware protection and casual VPN use across a few devicesnot Authy
  • Hiding browsing activity from an internet service provider or a shared network operator rather than defeating a determined adversarynot Authy
  • Occasional access to region-locked content where a dedicated streaming-focused VPN would be more product than the need justifiesnot Authy

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Authy

  • There is no export function for stored TOTP secrets, so moving to a different authenticator means disabling and re-enrolling two-factor authentication on every account individually, which is the reason most users stay rather than a reason anyone should choose it.
  • The Windows, macOS and Linux desktop applications were discontinued in 2024 and stopped working, so any workflow that depended on copying codes on a computer now requires a phone in hand, and users who held tokens only on a desktop client had to restore from backup or re-enrol.
  • The account is keyed to a phone number, so an attacker who takes over that number through a SIM swap can begin the device registration flow, and the only remaining control is the backup password that most users set once and cannot recall.
  • In 2024 an unauthenticated Twilio endpoint allowed attackers to confirm which numbers from a supplied list were registered Authy accounts, exposing around 33 million phone numbers, which disclosed no codes but handed phishers a validated list of people known to use two-factor authentication.
  • It is a free consumer application inside a company that has already retired the paid Authy developer API it once supported, so it carries no revenue of its own, and users should treat its continued existence as a business decision rather than a roadmap commitment.

Bitdefender VPN

  • The network is not Bitdefender's: the servers and the Catapult Hydra protocol are licensed from Aura, formerly Pango and AnchorFree, so the company physically handling your traffic and subject to legal process is a United States based third party, not the Romanian vendor whose brand is on the client.
  • Catapult Hydra is proprietary and closed source, so unlike OpenVPN or WireGuard there is no public implementation for researchers to audit, and a buyer choosing on cryptographic grounds has nothing to inspect.
  • There is no published independent no-logs audit of this service comparable to the Deloitte, PwC and KPMG engagements the standalone VPN vendors commission, so the no-logging position rests on the privacy policies of two separate companies rather than on any external assurance.
  • The free tier bundled with the antivirus suites is capped at a small daily allowance and selects the server for you, so it is a demonstration rather than a usable VPN, and customers who assumed their suite included a VPN find they need a further paid upgrade.
  • Feature depth is well below the dedicated market: no port forwarding, no dedicated IP, no multi-hop, no city-level server selection and no Linux or router client, so routers, NAS devices, consoles and anything needing an inbound connection cannot be covered at all.

Answered from the vendors’ own pages

Authy: Is Authy still supported?

The mobile apps for iOS and Android are still available and functional. The desktop applications were withdrawn in 2024 and the Authy developer API has been retired in favour of Twilio Verify, so the surrounding product has been shrinking.

Bitdefender VPN: Who actually operates the servers?

The underlying VPN network and the Catapult Hydra protocol are licensed from Aura, previously known as Pango and AnchorFree, the operator of Hotspot Shield. Bitdefender identifies the arrangement in its VPN terms. Your traffic therefore passes through a United States based provider's infrastructure.

Authy: Can I export my tokens?

No. There is no export of the underlying secrets, by design. Migrating to another authenticator means going to each service, disabling two-factor authentication and setting it up again with the new app.

Bitdefender VPN: Is the free version enough?

Only as a taster. It is capped at a small daily traffic allowance and chooses the server itself, which rules out streaming and any sustained use. It exists to demonstrate the feature inside the antivirus suite.

Authy: What happened to the desktop app?

Twilio announced its discontinuation in March 2024 and the applications stopped working later that year. There is no replacement desktop client; the mobile apps are the product now.

Bitdefender VPN: Has the no-logs claim been independently audited?

There is no published independent no-logs audit of this service equivalent to those commissioned by the dedicated VPN providers. If an audited no-logging claim is what you are buying, this is not the product for it.

Authy: Is multi-device sync safe to leave on?

It is the feature most worth understanding. Leaving new device registration enabled means anyone who controls your phone number can attempt to add a device. The usual advice is to turn the multi-device setting off once your devices are registered and turn it on only when you need to add one.

Bitdefender VPN: Does it work with streaming services?

Sometimes, but it is not built around that use case, there is no per-service server labelling, and there is no commitment to restoring access when a platform blocks a range. A streaming-focused provider is a better fit if that is the reason you want a VPN.

Authy: What if I lose my phone and forget the backup password?

The secrets are encrypted with that password and Twilio does not hold it, so they cannot be recovered. You would fall back to each individual service's account recovery process, which is exactly the situation the backup was meant to avoid.

Bitdefender VPN: Can I run it on Linux or a router?

No. There is no Linux client and no router firmware or manual configuration option, so coverage is limited to the Windows, macOS, iOS and Android clients.
