Security and insurance

Security Overview

Your security is our priority. All data transferred and stored within our systems is protected with military-grade 4096-bit encryption.   

For additional protection, we offer two-factor authentication (2FA). You can enable 2FA in the Settings of M1.   


M1 Invest Account Insurance  

M1 Finance LLC is a registered broker/dealer with FINRA and a member of SIPC.  

SIPC (Securities Investor Protection Corporation) protects against the loss of cash and stocks held by a customer in their brokerage account (M1 Invest). SIPC does not protect you from any decline in the value of your securities.

SIPC protection of customers with multiple accounts is determined by "separate capacity." Each separate capacity is protected up to $500,000 for securities and cash (including a $250,000 limit for cash only). Accounts held in the same capacity are combined for purposes of the SIPC protection limits.

Examples of separate capacities are:

  • individual account;
  • joint account;
  • an account for a corporation;
  • an account for a trust created under state law;
  • an individual retirement account;
  • a Roth individual retirement account;
  • an account held by an executor for an estate; and
  • an account held by a guardian for a ward or minor. 

More information about multiple accounts coverage can be found here. Explanatory brochure available upon request or at

Certain accounts clearing through Apex Clearing also have supplemental insurance if SIPC limits are exhausted.

In the event of insolvency at Apex Clearing, claims that exceed the standard SIPC limits may be able to make a claim against Apex Clearing under their excess insurance policy. That excess SIPC policy has an aggregate limit of $150 million across all Apex Clearing accounts, subject to sub-limits per each individual customer of $37.5 million for securities and $900,000 for cash to protect customer assets. 

Since cryptocurrencies are not covered securities, Crypto Accounts are not protected by SIPC insurance.
