Personal wallet access
Seed: is used to restore the wallet in case of loss of the device or other problems (it represents the main key that contains your funds and must not be shared with anyone)
Password: is used to unlock the wallet at device level and authorize transactions, it is NOT a copy of the seed
Fingerprint or FaceID (iOS users): used to unlock the wallet at device level in read-only mode, it is NOT a copy of the seed
Access to EidooID service
It's done through the combination email + password, which does NOT allow you to access the wallet and can NOT be used to recover funds in case of loss of the seed. Eidoo doesn't save a copy of the seed on its servers and cannot access your wallet.
