Solution 1

You can use the firebase-cli by writing firebase auth:export save_file.csv --format=csv or firebase auth:export save_file.json --format=json

More details can be found on the firebase documentation page: https://firebase.google.com/docs/cli/auth#authexport

Solution 2

I did not get any option on firebase console UI. So you need to install firebase tool using npm.

npm install -g firebase-tools

and then login using

firebase login

after login you need to run one of command

CSV Format

firebase auth:export save_file.csv --format=csv --project <project-id>

JSON Format

firebase auth:export save_file.json --format=json --project <project-id>

you can get the project-id from home screen of firebase console

Solution 3

ex corret firebase auth:export save_file.csv --format=csv --project=my-name-project-fb

I use email/password authentication for my Firebase.

I’m considering moving to a different backend and I’m wondering if there is any way to export user emails/password hashes so that I can authenticate them outside Firebase?

I would also need to know the hashing algorithm.

I’ve tried firebase auth:export save_file.json --format=json, but I didn’t get the hashes: { "localId": "020f4fb0-0344-4ff7-bc47-b5e42b00b717", "email": "[email protected]", "createdAt": "1463657902000", "providerUserInfo": [] } Since many of my accounts are created in early 2016, I suspect passwords were not hashed using the scrypt algorithm which is required as per note at the beginning of auth:export command’s docs.

In any case, I accept this answer because I guess it would work with this recent platform.

Once you export the users & hashed passwords, you can use github.com/firebase/scrypt to verify user logins.

is there any way to export just the users that have an email attached to their account?

Any idea why when I run this, it works, but in console it keeps repeating the message Exporting accounts to auth_export.csv ✔ Exported 289 account(s) successfully. ✔ Exported 289 account(s) successfully. ✔ Exported 289 account(s) successfully. ✔ Exported 289 account(s) successfully.

And the exported file ends up containing the data repeated several times.

It is usually best to explain how your answer addresses the question.

Same issue here, it seems to endlessly loop/append repeating data unless you cancel the command after the first success message

Is there any chance that this CLI command will include custom-claims in the future as well?

This may be a bit of a stupid question, but where is the exported file (save_file.csv or save_file.json) saved to? I get the message that Exported 56 account(s) successfully but can't locate a save_file.csv on my local PC.

For me, it's always in the same folder I start the script from.

When I run firebase auth:export I get "An unexpected error has occurred. "
