| <xref:Microsoft.AspNetCore.Identity.PasswordHasherOptions.CompatibilityMode> | The compatibility mode used when hashing new passwords. Defaults to <xref:Microsoft.AspNetCore.Identity.PasswordHasherCompatibilityMode.IdentityV3>. The first byte of a hashed password, called a *format marker*, specifies the version of the hashing algorithm used to hash the password. When verifying a password against a hash, the <xref:Microsoft.AspNetCore.Identity.PasswordHasher%601.VerifyHashedPassword%2A> method selects the correct algorithm based on the first byte. A client is able to authenticate regardless of which version of the algorithm was used to hash the password. Setting the compatibility mode affects the hashing of *new passwords*. |
| <xref:Microsoft.AspNetCore.Identity.PasswordHasherOptions.IterationCount> | The number of iterations used when hashing passwords using PBKDF2. This value is only used when the <xref:Microsoft.AspNetCore.Identity.PasswordHasherOptions.CompatibilityMode> is set to <xref:Microsoft.AspNetCore.Identity.PasswordHasherCompatibilityMode.IdentityV3>. The value must be a positive integer and defaults to `10000`. |
