Authenticator apps support sign-in verification, with differences in code type, backup, syncing and administration. Compared on code type, encrypted backup, free plan, multi-device sync, paid from, push approvals, supported platforms and team administration, the entries can be assessed against individual or team needs. LoginTC, Proton Authenticator and Duo Mobile are among the options to compare. Check supported platforms and verification methods against the accounts and devices you use, then weigh backup and sync for maintaining access.
