Elders often grant immortality as a gift to humans who have helped them. Since this type of Immortality can be revoked with a mere touch, immortals often become servants to Elders. Dark Elders use this leverage to control agents such as Dr. John Dee and Niccolo Machiavelli.

Some powerful beings are capable of bestowing immortality onto humans. Some Elders, such as Aten, Tammuz, and Quetzalcoatl are capable of granting immortality. The Earthlords Isis and Osiris also wield this power, which they used to control Dr. John Dee for centuries.
Elixirs of ImmortalityThe Codex also contains a recipe for a temporary elixir of immortality which lasts for roughly one month. The recipe changes every time, and using an old recipe will actually speed up the ageing process. This method of immortality has sustained Nicholas and Perenelle Flamel for centuries, though once Dr. John Dee steals the codex from them in The Alchemyst the two begin to age at a rate of roughly one year per day (or faster, when their auras are used).
The Comte de Saint-Germain claims to have discovered and perfected a recipe for immortality that did not need to be renewed every month. However, given Saint-Germain's dubious character, this may not be entirely true.
Some spells can grant immortality. Abraham made Gilgamesh immortal (albeit in a flawed way) using a spell contained within The Codex. It is likely that Abraham made Tsagaglalal immortal using a spell as well, however she retains the use of her aura and her memory, which would indicate that the spell was further perfected after Gilgamesh.
Some substances can grant immortality. Injecting vampire blood grants immortality (and does NOT turn the human into a vampire) - Joan of Arc gained immortality upon receiving a blood transfusion from Scathach which was meant to save her life after she was nearly burned at the stake.
