4 Random digit to eeprom

Projects Programming
1

Hello I just want to ask if it's possible to generate 4 digit random number and store it in eeprom.

What I want to do is to generate one random 4 digit number say "1294" and store it in eeprom so I can use the data for my code.

Lastly each time a random 4 digit number is generated , it will overwrite the one that's in eeprom.

Thank you.

Yes.
But be aware that there is a write limit on EEPROM of 100,000 times. What is wrong with a normal variable?

I want to use the random function to store a 4 digit so I can use it as a one time password, is this possible too?

Thanks you for the reply.
