Can I use the auth:import and auth:export tools with the Firebase Auth Emulator?

Question

I would like to preload the firebase auth emulator with my test user accounts whenever it starts up, the same way I do for the Firestore emulator with its import/export options. I tried using auth:import and auth:export while my emulators were running but it connected to our actual dev firebase project, and not the emulators. Is there anyway to run auth:import and auth:export against the auth emulator?

For reference, I am referring to these commands (https://firebase.google.com/docs/cli/auth) and this emulator (https://firebase.google.com/docs/emulator-suite/connect_auth).

Answer 1

The ability to do this has now been added to the firebase tools

The older answers still work and may be useful

https://github.com/firebase/firebase-tools/releases/tag/v9.1.0

Support emulators:export and import for Auth Emulator (#2955).

firebase help auth:import
Usage: firebase auth:import [options] [dataFile]

import users into your Firebase project from a data file(.csv or .json)

Options:
  --hash-algo <hashAlgo>               specify the hash algorithm used in password for these accounts
  --hash-key <hashKey>                 specify the key used in hash algorithm
  --salt-separator <saltSeparator>     specify the salt separator which will be appended to salt when verifying password. only used by SCRYPT now.
  --rounds <rounds>                    specify how many rounds for hash calculation.
  --mem-cost <memCost>                 specify the memory cost for firebase scrypt, or cpu/memory cost for standard scrypt
  --parallelization <parallelization>  specify the parallelization for standard scrypt.
  --block-size <blockSize>             specify the block size (normally is 8) for standard scrypt.
  --dk-len <dkLen>                     specify derived key length for standard scrypt.
  --hash-input-order <hashInputOrder>  specify the order of password and salt. Possible values are SALT_FIRST and PASSWORD_FIRST. MD5, SHA1, SHA256, SHA512, HMAC_MD5, HMAC_SHA1, HMAC_SHA256, HMAC_SHA512 support this flag.
