Will I lose my existing 2FA accounts if I switch from LastPass Authenticator?

No. Once you import your existing keys into Authium, they will run completely in parallel. You can test Authium and verify everything is working perfectly before disabling or removing LastPass Authenticator.

Is Authium really safer than LastPass Authenticator?

Yes, especially for desktop developers. Authium implements a zero-knowledge security model. Your encryption keys are derived on-device from your master password, meaning nobody (including Authium) can decrypt your vault. Some competitors sync vaults with weaker or proprietary cloud protections.
