Pro Tips

Export users with 'firebase auth:export users.json --format=json' for backups or migration to another project.

Import users with hashed passwords: 'firebase auth:import users.json --hash-algo=BCRYPT' preserves passwords.

Use the emulator to test auth flows without creating real accounts or sending verification emails.

Exported user data contains password hashes and sensitive info. Store exports securely and never commit to git.

Importing users with the wrong hash algorithm silently corrupts passwords — users won't be able to log in.

$ firebase auth:export users.json

Export users to JSON file

$ firebase auth:import users.json
