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.; Zencity social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • They diverge on capability: Authy covers Encrypted cloud backup, Zencity covers Organic social listening.
  • Prices and features above were last checked on 31 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.

Zencity

  • Social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • Government analysis of residents' public speech, particularly by police departments, has drawn civil liberties criticism and records request scrutiny in United States cities, and agencies need a public answer ready before signing.
  • Sentiment classification of local slang, sarcasm and non English posts is imperfect, and a misclassified theme presented in a leadership briefing can be acted on before anyone checks the underlying posts.
  • Survey sample sizes at neighbourhood level are often small, so the district level breakdowns that councils most want are the least reliable numbers in the report.
  • It reports on opinion without connecting to service delivery systems, so acting on a finding remains a separate manual process in whatever operational software the agency runs.

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.

Zencity: Is this surveillance of residents?

It analyses publicly posted content and aggregated survey responses rather than private accounts, but the distinction has been contested publicly, especially for police use. Prepare an explanation before procurement.

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.

Zencity: Why pair listening with surveys?

Because the people who post are not representative of the people who live there. The gap between the two datasets is often the most useful output.

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.

Zencity: What did Zencity acquire?

Elucd, in 2021, which brought community trust survey methodology used with police departments.

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.

Zencity: Can residents find out what our city bought?

Yes. These are public contracts and several have been obtained and published through records requests.

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.
