ASCO LastPass Best Practices DO Do save passwords you use in ASCO apps and services. Do user LastPass to auto-generate strong, random passwords. Do use the LastPass browser extension to auto-fill passwords for ASCO apps and services. Do use LastPass sharing if your work requires you to send a password to a colleague. DON’T Don’t save personal passwords in your ASCO LastPass account. Don't use solutions other than ASCO's LastPass to share ASCO credentials. Don’t use your browser’s built-in “Remember this password?” feature to save passwords for ASCO apps and services. Your browser does not store saved passwords securely. Use the LastPass Browser extension instead.
