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
Vim
- Configuration system uses keyboard mappings with no graphical interface for settings
- Requires browsing documentation to modify even basic settings
- Lacks sensible defaults for many common configurations
- Plugin ecosystem stability varies widely depending on custom configuration complexity

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 The desktop applications were withdrawn in 2024 and the Authy developer API has been retired in favour of Twilio Verify, so the surrounding product has been shrinking.
Vim: Is Vim free and open source?
Yes, Vim is free and open source, distributed under a charityware license. The creator requested donations to ICCF Holland, a non-profit supporting AIDS victims in Uganda. All donations are forwarded to ICCF.
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.
Vim: What platforms does Vim support?
Vim runs on Unix-like systems (Linux, macOS, BSD), Windows (7, 8, 10, 11), VMS, and is available through package managers or standalone installation on all major operating systems.
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.
Vim: Who maintains Vim now?
Vim was created by Bram Moolenaar, who passed away on August 3, 2023. Christian Brabandt is the current lead maintainer, and the project continues with volunteer contributors.
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.
