Digital signatures and digital credentials are a common security measure in digital wallets, a recent security study found.

The research found that only 10 percent of digital wallets store user-inputted passwords, and only 2 percent store digital keys.

However, these keys can be used to unlock digital wallets or store passwords.

These credentials can be easily forged and used for fraudulent purposes.

To solve this problem, digital wallets include a password vault.

Digital wallets have a password for the user.

If the user attempts to login, the password vault is used to protect the user’s digital wallet and credentials.

The researchers found that digital wallets with the password-vault feature use less than 1 percent of the storage space of existing digital wallets.

“We believe that digital signing and digital credential storage is a sign of security in a wallet, as it makes it much harder for the attacker to forge user passwords or steal credentials,” Dr. Michael O’Brien, lead author of the research, said in a statement.

The findings were published in a paper titled “Authentication in digital currencies.”
