The short version
- 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.; HCP Terraform legacy free version deprecated; no current freemium tier

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.
HCP Terraform
- Legacy free version deprecated; no current freemium tier
- New users receive $500 credit but still require usage to continue service
- Terraform Enterprise requires custom pricing

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 The desktop applications were withdrawn in 2024 and the Authy developer API has been retired in favour of Twilio Verify, so the surrounding product has been shrinking.
HCP Terraform: How much does HCP Terraform cost?
HCP Terraform uses per-resource pricing starting at $0.10/month/resource for Essentials, $0.47/month/resource for Standard, and $0.99/month/resource for Premium.
SourceAuthy: 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.
HCP Terraform: Does HCP Terraform offer a free tier?
No, the legacy free version has been deprecated. However, new users receive $500 credit to try the service.
SourceAuthy: 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.
HCP Terraform: What does the Standard plan include?
Standard plan at $0.47/month/resource includes unlimited modules, module deprecation, team notifications, no-code provisioning, and Waypoint templates.
SourceAuthy: 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.
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.
