How to create unique and safe UID on Admin- Custom Token- Firebase
up vote

I use custom auth function on my app, in order to login anonymous users (by saving a unique permanent custom token on their device).
The functions work fine both on app side and admin side but I need to provide a unique UID on the admin side- in order to save the user on Firebase.
Here's my code on Admin (index.js):
exports.createToken = functions.https.onCall((data, context) =>
const uid = "?????"; // how to create some unique uid here?
return admin.auth()
.createCustomToken(uid)
.then(customToken =>
console.log(`The customToken is: $customToken`);
return status: 'success', customToken: customToken;
)
);
- I need to create unique uid (that isn't on my Authentication users
table already). - It should be "safe" (that two users won't get it at the same time).

Thanks, there's also UUID. But I need some solution for firebase and admin- that would be safe

Have you considered using Firebase Auth and logging in anonymously?

Yes, but then it creates multiple anonymous users- multiple tokens. With the custom token I can be sure the device can't create more than 1 user on my db

anonymous user is more for a temporary login to the system- for example when buying something for a second. I need something that will stay permanent and custom token gives me this option
