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.; Doppler developer tier limited to 3 free users with per-user fees beyond that
- They diverge on capability: Authy covers Encrypted cloud backup, Doppler covers Secrets management.
- Prices and features above were last checked on 30 August 2026.

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.
Doppler
- Developer tier limited to 3 free users with per-user fees beyond that
- Team plan pricing ($21/user/mo) adds cost for large teams
- 90-day activity log retention may be insufficient for long-term audits
- Enterprise plan requires custom pricing conversation

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 The desktop applications were withdrawn in 2024 and the Authy developer API has been retired in favour of Twilio Verify, so the surrounding product has been shrinking.
Doppler: Do AI agents count toward my user limit?
No, AI agents and non-human identities receive free access across all Doppler plans, including Developer, Team, and Enterprise.
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.
Doppler: What is the difference between Team and Enterprise plans?
Team plan ($21/user/mo) includes SAML SSO, role-based access controls, and 90-day logs. Enterprise adds custom deployment options, unlimited config syncs, 99.95% SLA, and a dedicated account manager.
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.
Doppler: Can I rotate secrets automatically?
Yes, both Team and Enterprise plans support automatic secret rotation. Developer tier supports manual rotation only.
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.
